Mark is AMAZING! I was in the process of purchasing a car and took it to Mountain Muffler for a pre purchase check. Mark did an incredibly thorough check, identified multiple issues, gave us a repair estimate, and didn’t even charge us. Incredibly honest bunch of very talented mechanics. A must for your car!

It seems as though catalytic converters are very popular to steal right now. We have a small fleet of work trucks and we have had 3 of the trucks within the last year get the catalytic converters cut out. Mountain Muffler has replaced the cats on all the trucks. The last time this happened, Gary at Mountain Muffler offered to fabricate a cage to protect the cats from being stolen. He did this at a very fair price and the cage really worked! Our initial investment to have the cats replaced was over 4k. Several weeks after having the cage installed, someone tried yet again to cut them out yet again! They were successful at cutting the exhaust but due to the cage were not able to remove the cats! One quick call to Gary at Mountain Muffler and he was able to quickly weld the exhaust back together which saved us not only a lot of money but also time in waiting on parts which are often back ordered. Our truck was only down a day and we were back on the road. Gary and his team at Mountain Muffler are TOP NOTCH and I would recommend them to everyone!

Definitely a place for mufflers they also build cages to protect your Catalyc converters call them and give them a shot great service.

I have been going to Mountain Muffler for a few years now. Full disclosure the only services I have had Gary do for me were exhaust related. Gary is honest and knows what he is doing. He is one of the few local shops that can actually custom bend pipe for exhaust systems. This may not seem like a big deal but, it really is. If you have any custom work that needs to be performed, bending is preferable to trying to piece together pre bent sections to make it work. I recently added an anti-sway bar to my vehicle and the bar interfered with the stock exhaust. Gary custom bent a section with clearance for the bar and welded it in place. Great work, looks great, performs as expected and now my car has an anti-sway bar. Win Win Win. I recommend Gary for any of your exhaust needs. Give him a try you will not be sorry.

Gary was truly phenomenal, helped me with an exhaust leak on my Tundra. A bolt broke off in the flange coming off the catalytic converter, he helped me remove it and reseal the exhaust with my factory muffler and tailpipe. Would strongly recommend for any automotive job, especially those exhaust-related.

I ran over a curb and dinged the bottom of my car. It started sounding very loud but no lights were on. I took it to Gary and he gave me an accurate estimate and got to work on it that day. He was friendly, informative, straight forward and you can tell he’s not in it to rip people off. I was so confident knowing we had someone that really cared and didn’t price gouge us. In the end my car was fixed at an affordable price and I’m happy. I highly recommend Mountain Muffler!

Fixed my muffler quickly and at a reasonable price

Great shop locally owned. Honest. 5-star quality and service. Thank you!

Gary and his crew are helpful and professional. Have had work done before. Quality service and fair price. Getting ready to schedule more work this upcoming week. Small business owner that delivers on his business.

I took my car to mountain mufflers to have a catalytic converter installed that was cut out from thieves recommended by a neighbor they were honest up front very reasonable price and able to get me in quickly compared to other businesses

This is a great exhaust shop! This is the 2nd time I went to them. 1st time was for a rock crawler 4x4 project. They can bend pipe and do custom work. It seems other. Shops have forgotten that art. On top of that they care about the customer and your budget and wont take advantage of you like so many other shops these days. They built a fully customized system for my Ram truck to my requests and I am very happy with the end result and price I was charged. Thanks!

Gary was great. He was able to cut out and weld in a new section of pipe to replace a broken section and get us back on the road in less than 30 minutes. Some of the other shops I called are only able to replace bolt on components, not weld. Welding the new section was more budget friendly. Thanks, Gary!

The owner isnt afraid to tackle any project. Thank you your the best!!

Gary is the BEST! Great customer service and very fair and honest pricing to repair an aftermarket exhaust that they didnt even install for me. I will forever be a customer moving forward!

Gary at Mountain Muffler is amazing. Professional shop run by an honest guy. Gary went out of his way to make sure I was taken care of and could get back on the road quickly. I drove all the way down from Grand Lake, and if I ever need any more exhaust work, Ill be sure to get it done at Mountain Muffler. Thank you Gary!

Really good shop run by a really good guy with lots of expertise. They do great work. Go here first.

Gary was fantastic! He accomplished my goals and came in less than his original quote. Also fixed a completely unrelated rattle that I though may have been related to the install without hesitation and for free!

Awesome! Broke down in the mountains and was able to get to the shop in Golden... got me in and out car works great!! Such a nice guy, honest, and gets the job done right! Highly recommend!!!

My experience today was very good !! Gary and Mark are excellent at what they do !!! Thanks again guys . Ill let you know what happens, Renee Meyer, orange dodge nitro .

Gary was amazing and very helpful after my work truck had its catalytic converter stolen. Great customer service

Unbelievable! I needed a quick fix for my tailpipe. It was rattling because I backed into a hill trying to get my older St. Bernard loaded up. They told me when they could get me in, up on the lift. A quick repair and I was on my way. Highly recommend these guys!

The rear exhaust pipe on my Coachman RV disconnected from the muffler on a very rough section of Highway 70 through the mountains. Driving down Hwy 70 my wife called Mountain Muffler and explained the problem and our location. Gary gave directions and stayed 30 minutes past closing. Used his outside lift (for RVs and tracks) - welded the exhaust pipe onto the muffler and also welded the broken bracket. Reasonable cost and on our way in 30 minutes and Gary got home late for dinner. Absolutely outstanding service! Thanks Gary BTW Midas and RV Dealers just gave us the run around and one even suggested we wait until morning when and possibly they could work us in.

Gary is an awesome guy straight forward and great service this will be my second time coming in to get my exhaust on my second truck I definitely recommend this place.

Friendly and professional. Highly recommend.

Just wanted to tell you thank you and I will highly recommend your business to anyone

Stopped by at closing time with a lot of frustration after having worked on our 91 Bronco all day. Gary welcomed us and all of our questions, diagnosed and explained exactly what needed to be done to our babe within moments, offered us his very next available time slot and had our work completed within an hour. Amazing all around!! From communication to cost. So happy to know this gem of a spot and person in our neighborhood.

They were honest and knowledgeable. Instead of convincing me to put in a brand new exhaust system they just fix the section of pipe that was broken and it sounds and operates like new. Knowing that I live a distance away, they were able to repair it on the spot and I did not have to reschedule or come back down the mountain again.

Mountain Motors is great! I had to have a section of my exhaust replaced, and Gary did it unbelievably quickly, and for literally a thousand dollars less than I was quoted at another shop. I recommend Mountain Motors to anyone that needs piece work done on their exhaust system.

We were driving through on our way to WP and RMNP for the weekend. Woke up this morning in North Platte, NE to the putt putt putt sound, which gradually grew into a PUTTPUTTPUTTPUTTPUTTPUTT annoyance. Realized the sound would disturb the wildlife and that just wouldn’t do. Called a number of places looking for help. Mostly got (understandably) laughed at when we asked if we could get a muffler today. Mountain Muffler understood our dilemma and kindly offered to take care of it if we got there right away. We got there right away (!) and within an hour, my new best friend finished one car, attended to another, and replaced our muffler for a *much* more reasonable price than I’d braced myself for. Honest, quick, professional, and great work. Highly recommended!

These guys are honest and do quality work

So they put on a Flowmaster series 40 onto my 2017 Chevy Silverado. It sounded OK but it was not what I wanted so I just went back the other day to put a super 10 Flowmaster onto the truck and removed the resonator. The truck now sounds perfect and it sounds like what I wanted. This crew is very nice and they do great work I recommend them if you’re wanting a muffler

I have taken 3 of my vehicles to them, all different kinds cars over the last 12 yrs and every time it has been an excellent experience. They work quickly, are honest and up front with needs worked on. I appreciate theyve always shown me the part or parts that got replaced and why, never felt tricked into fixing something that didnt need fixed. I recommend this business to everyone.

Gary goes out of his way to get you a fair price and quality work. Definitely recommend to anyone.

I ran over a cut off metal post that ripped a huge gash in a section exhaust pipe. Another shop offered to replace the whole thing but they werent equipped to repair just the damaged section. Mountain Muffler cut out the severely damaged section and welded in a new one that he made on the spot!Friendly local business man that does excellent work at a very reasonable price! Im glad I discovered him and I definitely recommend this shop!

If you are looking for super honest, nice, professional, and capable mechanics that are also affordable. Go here!!

Very friendly and helpful

Best experience ever, they installed a catalytic converter for me, saved me money, got me in fast. My vehicle was ready for an emissions test before the guys across the street could make my tacos. I highly recommend you taking your vehicle in for your exhaust repairs. They also do other vehicle repairs. Im giving him *********** stars! Thank you so much!

Giving Mountain muffler the hight review cause I was told by a few happy costumes that do great work

Great prices and quick turn around. My #1 shop for exhaust work

10 ⭐. People like Gary make me realize that there is still hope in Humanity and some people love what they do! Thank you sir!

These folks were great! I will come back again and I would recommend them for exhaust work.

Got Garys number from a friend of mine and he said he was the best. Even though I could of done it myself it was worth a 40 min drive from me to know my baby was in good hands. Not only is he very friendly and knowledgeable but hes straight up with you about everything as well. Definitely I recommend him if anyone asks me if I know a good muffler guy.

Great work, for a great price! This will be my go-to muffler shop from now on!9 month update: welds are still as solid as a rock. Couldnt possibly be more satisfied!

Thank you for getting my sons car in and getting it done so quickly! I am really happy with my experience at Mountain Muffler and the work that Gary and his team did! Very honest and affordable! I would highly recommend them!

I like the people at Mountain Muffler. They are always ready to assist with repairs. I recommend them to everyone that needs muffler repairs.Thanks.JP Berry

I recently had to get some muffler work done on my car, and at a prior mechanic shop they told me that it would cost about $560. I went to Mountain Muffler and they were able to take care of the problem for around $170. They saved me a lot of money, were extremely professional, and I would highly recommend them to anyone!

Mountain Muffler recently helped me figure out a issue with my Subaru. Much thanks to Gary and the great team at Mountain Muffler. Would go back anytime I have an issue.

Going forward, whenever I have questions about my vehicle, Ill definitely be giving Gary a call. EXTREMELY HELPFUL when I was calling while on the road to explain all the details of what was going on with my vehicle, what it needed in order to be fixed, and what it would cost.Small town kind of service and Gary is definitely someone to trust with your vehicle. Very glad I gave them a call and brought my vehicle in to them!

Took my 62 Pontiac Grand Prix in. Gary did a great job of explaining my options, and installing a new exhaust system, including MagnaFlow mufflers that sound great!

Gary has now done a custom exhaust on my truck as well my dad’s and buddy’s. They all look and sound amazing. Super friendly and gives honest, helpful advice towards whatever work you’re looking to do on your vehicle. Highly recommend! Thanks again Mountain Muffler!

Gary took my call at 8:30 and had me in his shop and finished by 10:00. Knowledgeable, and cost conscience without being “cheap”! Great retro feel shop, with retro style service.Quick and quality service, great combination!

This place is great. Good work. Fair price.

Gary did another great job today. Never disappointed, if you dont know now you know.

What a wonderful place. We were on a trip from out of town with a vintage car and Gary was able to squeeze us in. Great job, good price. We would highly recommend them!

Highly recommend Gary and Mountain Muffler. Excellent diagnosis and communication of cost. Gary is extremely knowledgeable and forthcoming with as much detail as you want about the work and parts to be installed. Work was done with high quality and timeliness.

Called about doing a custom exhaust on my 1985 land cruiser with a V8 swap. I saw the work he did on my buddies 77 truck and thought it was good enough to pull the trigger. He told me he couldn’t work on it because it didn’t have the emission stuff on it....I called for him to be the one to put the cats and exhaust on it? Kinda confused, pretty rude guy that obviously doesn’t want work. His name was Gary. Guess I should have called after he got his coffee.

Gary was GREAT! He worked with me to find an affordable option to repair my exhaust system.He personally did the repair for exactly what he had quoted me. He got me scheduled quickly and completed the job quickly as promised!I observed him working with other customers that were having budget issues and he went way out of his way to save them money without compromising safety or quality! You don’t see service like that with the big chains!I’d highly recommend Mountain Muffler and they will have all of my business now and in the future!Thanks Gary!! My 1990 Chevy sounds great and passed emissions with flying colors! I looked at the welds and supports and was very impressed!TONY S.

Helped me quickly in a pinch. Solid guys and work!

Gary is the most genuine guy I’ve ever met!

Awesome quality work. My wife and I were passing through and had exhaust problems on our van and we found Gary at Mountain Muffler on Google and waited for him to open. When he arrived just before time to open I asked him to help us out and he said his schedule was packed but he found a way to fit us in almost immediately . Great work and great service. Thanks again Gary.

I highly recommend this place. Its very hard to find people who you can trust to work on a car who dont try to rob you on the bill. These are ethical people who work honestly at fair prices. I had a complicated vibration/rubbing issue and they resolved it

I can’t say enough good things about Mountain muffler, and Gary. I would give them six stars if possible. I was looking at a repair that was approaching $1000. Gary was able to effectively diagnose and repair(while I waited) the problem for a fraction of that($175.00).They never tried to upsell or fix things that didn’t need fixing, a real straight shooter! Honesty and integrity are the foundation of this business.

Gary did an awesome job on my 1969 Mach 1 Mustang. Reasonable price, excellent work and they got the job done quickly. Highly recommended!

Outstanding service, quality, and price. Would go back without a second thought and would recommend to anyone.

I recommend this place because, it is a good place and my muffler has worked even better than ever. He is also a friendly guy.

If you need any exhaust work done on your vehicle... This is the best place to bring it. Gary the owner is the most knowledgeable most helpful & honest auto repair owner I know. If its not in his scope of repair, he will send you to someone he trusts. I am really impressed with the way he does business & you will be too.

Best service I have ever received. I called Gary out of the blue, 10 min later my truck was up on the rack 5 minutes later he diagnosed the exhaust, cut and welded. Sent on my way! This is how business is done!

Gary who runs the place (I think) did a great job on my simple low cost mod. I’ll be back when I upgrade again! Mod only took about 2 hours and he even took the time to paint the pipes so they match the undercarriage, which I didn’t need to ask for.Great place, with affordable prices and fast service!

Gary is the Man!!! I have now taken my second vehicle over to them to fix the exhaust. Both times i have been very happy with the knowledge, service, craftsmanship of the work is nice and clean and pricing.I dont usually take me cars to shops unless i have no choice and I can honestly say Mountain Muffler is my first choice from now on!!!Thanks Gary!!!!!!!!!!

Had an awesome experience here. I had them do some work on my rusty old muffler and then came back a couple weeks later for some further exhaust repairs. They are always very upfront and can tell you exactly what needs done. Good people, great work, and all around an awesome experience. Would highly reccomend for all of your exhaust needs.

Needed someone to run a quick mechanical check up on a 1996 F150 I was looking to purchase. Gary said he doesnt do this kind of work but quickly gave me 2 recommendations for places near by.

Did a fantastic job on my BMW e36! Gary is the man! Highly recommended for any and all exhaust fabrication. 12/10

Based on these great reviews, I took my Toyota Highlander to Gary for an exhaust issue. He executed a quality repair in less than 24 hours for a whole lot less than I would have paid anywhere else. You cant go wrong with Mountain Muffler

Great service and great work. This is the perfect local shop that you could only hope to find! Yes, this is the place. I had a new muffler and tailpipe installed on my 2000 Jeep Cherokee along with brake pads and rotors. A pleasure to work with these guys, and they have the most awesome sign out front.

Mountain Muffler is amazing! They are so helpful and very quick with their service. I was quoted over $1,500 at another repair shop - but Mountain Muffler was able to fix my Jeep for $350! They look for all options to save money and make your repair experience easy! I am absolutely amazed by the service at this shop. I will continue to take my Jeep here to be serviced and recommend them to anyone who needs work on their car. I highly suggest becoming a Mountain Muffler customer!

Awesome experience. I ordered a new Borla exhaust system, to put on my wife’s Ford Raptor, as a surprise. He got me in same day and did a fantastic job. Thank you!

About ten years ago had a new muffler system put on my 84 pick up. Noticed a hole a couple weeks ago, possibly from who knows what puncturing the muffler and they fixed it quickly and free. I appreciated the treatment and fast service even after so many years.

Great service had a small issue after I got it fixed and they were happy to take care of it at my soonest convenience holy recomend best muffler shop Ive ever been to!

Gary was FANTASTIC! We were stranded and none of the chain places could get us in. He was honest, fast, and reasonable. THANK YOU!

Best mechanic Ive ever had the pleasure of meeting. Great, honest work at the right price. 10/10.

Sheared a bolt off of my front brake caliper when I was attempting to replace my own rotors. Took it in to Mountain Muffler and they fixed my mistake quickly and cheaply. Gary was very nice and helpful. I will definitely come back!

Fast and friendly service. Saved me a ton of money!! Highly recommended

Gary is a very knowledgeable, skilled, fair, and down to earth guy. Went to multiple places to diagnose my running rich issue and he was the only able to fix it and get me past emissions. Would recommend to anyone and already have.

Phenomenal service and quality technicians. Gary was awesome! Great price and extremely fast work.

Gary is the Man !!! We came in (from off the road) and he quickly gave us an affordable quote and had the job done that same day (1 hr.) :) And did a very professional job too and got us back on the road smiling all the way. This is one place Id take a car or truck back to for sure! Every community needs honest and efficient business folks like this one . Thanks Dan from Ohio.

Been coming here for years. This is the first place I come to when I have a problem with my Jeep. Gary is friendly, capable, and creative and I always leave satisfied. Thanks for the great job!

Treated with respect! Very reasonably priced. Easy repair saved me tons of $ they didnt try to sell me an entire exhaust system!

My muffler started having issues when I was traveling here from out of state. They patched it up quick with a weld and I was off again. Great price on it too!

This place is awesome! I called them today after I had my exhaust system delivered this am. They got me in and out within an hour and the the work was extremely professional and courteous! They installed a gibson sport dual exhaust dual side exit on my 2017 tundra SR5 off road 5.7L. The truck sounds mean and noticeable power gains and fuel economy. Thank you Mountain muffler for the exhaust work and going the extra mile!

The best service and the best work I have ever received ..he helped me over the phone and then he did the work right when I got there. A good man

Very good shop, awesome job in a short time too!!

We had a great experience getting a muffler replace on our Dodge Diesel pick up. I called to check for a price and Gary told me if I would like to come in he will hold off lunch and check to see what I needed. That was 11:45. I got to his shop about 12:15, he finished helping a customer and immediately checked out what I needed. Although this was an unusual muffler he just happened to have one that matched exactly, He immediately gave me a fair price and skipped his lunch and had it fixed and installed in about 1 hour. Great service at a fair price. Thank you Gary!

Appointment easy and convenient. Done with a partial muffler pipe, rotors and brake pads in two hours! Gary the manager is fair and honest.

Theses guys are super friendly and do great work. Ive been going to them for silly exhaust work on my turbo Hondas over the last couple of years and Ive had nothing but great experiences. I generally dont trust auto shops but theses guys are honest and fair. If youre local in Golden I wouldnt consider anywhere else.

Price was awesome work was great as always highly recommend

I wanted to have my 2003 F-250 7.3 diesel exhaust system upgraded and Gary gave me great advise on an MBRP system. Mountain Muffler provided superior installation, all welded no clamps, at the best price on the internet. Now my truck sounds awesome and has more power. Thanks Gary and Mountain Muffler, I highly recommend your business.

Its refreshing to find an honest mechanic who will take the time to explain what is wrong with your vehicle and the parts required to fix it. Gary turned my car around in an afternoon and I passed my emissions test!

Awesome!! great price, great customer service, great on timing, just an all around great experience! subaru wanted almost triple what mountain muffler charged me and they did an amazing job. im a local and will definitely return and strongly recommend!!

5 Stars! Gary installs fast, first class exhaust systems for a good price. He treats your custom car or hot rod like his own - you wont be disappointed!

Gary at Mountain muffler...is... Awesome!Mechanics are known to be shady, NOT Gary! I was in a tuff bind and he was nothing but helpful and honest. Really went way above and beyond.He replaced two cats on my baby, 03 Xterra, it runs better, more power and passed emissions.Gary my friend, you have a customer for life
