JRs was the only shop in town I could find to repair the exhaust on our 2.5 ton deuce. The repair was quick and the price was fair and unchanged from the estimate. i also had the exhaust on my truck reworked and the service was timely, affordable, and professional. Well run shop.

Have all my vehicles serviced at Jrs, very happy with the fabulous professional mechanic work performed. Just great environment with timely work done!!!

The Best Mufler Shop in Town. JR does it tight and right. Old School Cool. Helpful Friendly Staff. Done in a timely manner with the right price. JR also does mechanical work on vehicles. There is also a used car lot on site. Great Location. I would recommend this Shop to Anyone and Everyone. Be There or be Square.

JR and crew do excellent work. I brought them a 13 year old truck that had been abused in every salty environment the east coast could throw at it. I do most of the work on it, so I knew I was bringing them a challenge for replacing my catalytics and headers. JR knew that instantly on first inspection and willingly took it on. They communicated exactly what they were doing as they worked and were great to do business with. I was also pleasantly surprised by their pricing. Great shop, thanks again guys.

Took a long time to get part and didnt get right color. Need more work done to car and they are reasonably priced. Nice staff

Huge thanks to Jrs Repair and Exhaust in Billings Montana! We only had one day in town, and they got us going in time! They fabricated a custom down pipe front he exhaust manifold and now she purrs like a kitten again!!!!On the road again!!! And no CO sensor going off warning me that Im killing my family when we idle the motor!!!!

Excellent and timely. Very good communication and fair prices.

Always very helpful, gets the job done

They were able to get my kids car in on short notice for a block heater done on time great price. Would highly recommend.

Very awesome work and great people 👍😁

Best automotive repair shop in Billings, especially for Subaru!

Great service. Work was done in a timely matter. Staff very personable

My car wasnt running and I took it in there and they fixed it right away and it only cost $58

Wouldn’t recommend, friendly people. Bad work, ruined my exhaust and muffler

Awesome place and they do what YOU like!

Ok, bit pricey

Greatest!

Great work, friendly and honest

Super-fast service. I brought a fire-fighting bus for service on damages to the exhaust. It took Interstate Exhaust less than 20 minutes, and Im on my way back to the fire camp. IM VERY IMPRESSED WITH GREAT QUALITY SERVICE.

These guys are phenomenal! Theyre very detail oriented and will get right down to an exact rattle. Not overpriced by any means.

Great Service

Excellent customer service! I called this morning and they got me in by 2 pm. I was expecting to have to purchase a new muffler, but Mike said no you dont need a new muffler. Your muffler is stainless and no holes. It just needs to welded back. Thank you for your integrity Interstate performance Exhaust.

Shout out to Mike and his crew. Got my car in without an appointment and fixed it same day!! Big thanks!!

Its a good place to get you car or truck fixed right.

Excellent work, higher prices but it shows when you see the work done its worth it, wish they communicated better on their plans before starting

I had a great experience. Mike was cheery and welcoming on the phone and took great care of me when I ran in to a jam with my motorhome.

Got my car in and out quickly. No pitch to add stuff not needed or wanted. Straight professionalism.

Great job welding support hangers on to exhaust pipes. Also great customer service will be back if any more work required.

Awesome experience! People were very friendly! I was driving across country and broke down here in Billings Montana, the catalytic converter was plugged and another shop wanted over $4000 to repair the vehicle. Interstate charged me less than $300 to repair it. I was able to get back on the road and continue my trip. Thank you so much, Definitely worth trying if you need something fixed!

Extremely happy with my visit! I called a few other places in billings that didn’t really sound like they wanted to sell me anything.Theese guys answered the phone with enthusiasm ready to get me what I wanted. Same day appointment!!!Not only does the exhaust sound amazing but the mechanic who worked on my pickup came out from the back to explain to me what he did. I was very surprised to hear him talk to me about how proud he really was of his work. He got right down to the detail and explained to me how special the bends in the pipe were and why his is the best!! I’ll definitely be back!!

Asked them to make custom exhaust firmly Ken-worth and they said they could it. Told them what I wanted 5 all the way back what measurements couldnt change. Went to pick it up when said it was done and saw they did everything that I asked them not to do and did nothing that I wanted except add to flanges. Never will go there again.

If you want the best go see these guys! Solid workmanship back by years and years of experience!

Best shop in town, especially for exhaust systems. Always go above and beyond. Straight and to the point mechanics. Never have to worry about price gouging.

THANKS to Ryan, Lena, and even you Bobby. I am so pleased with this experience. My 99’Audi A4 hasn’t run right for a little over a year now, and 2 other shops in town have tried to fix her up-and after I pay them- my car runs pretty much the same crappy way. Super frustrating and felt like such a waste of $! I was about to give up on a once very reliable and paid-off vehicle. It is fixed now and runs great! Dropped it off at 1 and they had ready for me before closing. Great job guys. Thanks

Very helpful. Great work and a good price!

Took my car there over a decade ago completely forgot about them doing my exhaust and brakes otherwise I would have taken my new car there the first time to have my exhaust done! My Scion tC no longer sounds like a Subaru and the raspiness has dramatically been reduced. They did the best possible no more glass pack could be installed because theres simply no where else to put it. Ive been to Midas and even Mufflers N More which I believe is their sister company but still both myself and my boyfriend had not been fully satisfied with the results. Until after we took it to Interstate, Bobby helped us out and Aiden a trainee with Mike did the work and the result completely satisfying.

Great guys, did my job for right on the spot, and knew their stuff

Great service 👍 new exhaust and muffler, so quiet now! Thank you!

Great service, Mike is awesome. Helped me with my car situation.

Exhaust looks great and great price. Wouldnt go anywhere else

Love the mechanics there, owner rocks

Had my truck driveline rear seal replaced. They ruined the front seal reinstalling the driveline. I took it back and they charged me. Then I took in a carb to get rebuilt. He called me to tell me it was ready and told me itd be between 200-250. I showed up an hour later and they charged me $370.

Had them do exhaust on several vehicles and they have always done great work and always done fast and right the first time, just had them do my Jeep Wrangler and it sounds great and the performance is greatly improved, good guys great prices and fast service what more can ya ask for

Great people and quick repairs.

Very good work done quickly

They are VERY PERSONABLE and are professionals.......

This business lacks customer service! Very rude owner who hung up the phone on their customer when he was questioned about a 200% mark up on an alternator. Do not take your business there.

Stoped on Saturday were closed but there and fixed me up.

Very helpful..

Good service
