Steve does great work. He takes the time to do it right. A very popular place for exhaust and repairs. I will definitely use this shop for my repairs. Thank you Steve.

Im not able to give the general public my experience with West Coast Muffler of Concord because every time I called (3 times) no one never answer the phone. I never received a return phone call after leaving a message as well. Therefore, I decided to call Mission Muffler of Hayward.My telephone call was taken and my questions answered. With that being said, I was able to go to Mission Muffler to have my high performance exhaust system installed with spintech mufflers at a fantastic price!

Good place, competitive prices and gets the job done. I was looking for a new place to take the car whenever I do need work done which isnt to often. Came here for an x-pipe. He got one from his shop and welded up the rest of the piping. Quality work and I will definitely come back for any other jobs needed.

Very good place to have your car worked on. A honest business that knows how to repaire your car. Been using them for more than 30 years Steve is a great guy and a good guy to work with. Your car has a problem call Steve .

Place is awesome and affordable... This place also has the bonus of always having something really sweet parked or on the rack...

Fast, friendly, efficient & affordable! I have, and will, continue to recommended West Coast Muffler to family & friends.

Steve and the West Coast Muffler crew are the best! They took care of me back in 2007, and they took care of me again in 2021. I wouldnt go anywhere else. Exceptional customer service!

West Coast muffler is the best place in the Bay Area. They do the best work and handle Business very professionally. They work very hard here and always keeps it 100 with you. Thanks Steve and Staff !

If you want quality at a fair price see Steve. Best systems around.full service and super on Hot Rods/Street cars.

Needed a catalytic converter for a Ford Expedition and West Coast Muffler and Tire did a great job.

Steve is amazing and knows his cars if you have an old school and you need some work check him out

I needed some custom pipe bending done and the only place in Contra Costa that would even consider the job was West Coast Muffler. Steve and Dave are fantastic! Thanks for the great job! I would definitely recommend this business!

Great place and professionally hook up your exhaust system modify your horsepower

Always excellent service and high quality work. My dad and I always bring our cars here for exhaust system work, the latest being my 2000 Ford Excursion for a catalytic converter. Past cars I’ve brought here were my 1936 Chevy Pickup, 1990 Jaguar XJS V12, 1997 Dodge B3500 van, and 2002 BMW M5; all for different types of exhaust work.

Absolutely The Best Shop In The Bay!

Took me in for last minute smog.Was very fast, and Was let know that there was a recall on my vehicle, something dealer never notified me about.Great job.

Great customer service, honest desire to help. My catalytic converted was stolen and West Coast Muffler was the 4th shop I reached out to. I was told what I can do to save money I didnt need to spend. The work on top of that was grade A work and I highly recommend this shop for any services you need that they offer.

Contacted Steve and left a brief message on doing some work done on my exhaust, next day he called me up and put me down for the day I had suggested in my message. I had a bad tailpipe and resonator with multiple holes from Wear and tear over years. I wanted to slightly modify it but staying true to the original sound.I had a vision and within a few hours hand crafted my pipe and did some extremely professional work and exactly what I had visioned at a incredible price.

Great shop! Steve is fantastic and is very honest with the customers! I recommend West Coast Muffler to everyone!

Went to a popular place in Antioch. They told me it was going to cost a crazy amount to fix my truck. Steve did it for less than half of the other place.

Super helpful, professional, and above all, honest as hell.

Steve is incredibly helpful and kind working on a couple of exhausts. The exhaust they made for my car sounds awesome.

Friendly, trust worthy service!

Several years ago, the exhaust pipe on my 95 Del Sol Vtec got snapped on the freeway due to debris I couldnt avoid. Concord Honda wanted to charge me 350.00 just to tell me they couldnt do the repair. I asked my chiropractor, Dr. William Haley (whos awesome) who he could recommend to repair my car. Without hesitation, he recommended West Coast Muffler, and said they had done wonderful work on his cars. I called them, and had my car towed there. Apparently, my car originally had a curved pipe leading to the muffler. I got a call about an hour after they got my car, and I was told they could custom make another curved pipe, but that it would be far cheaper, and just as stable, for them to put on a straight pipe. The difference in price was about 400.00. They could have just done the more expensive job. I wouldnt have known any better. But they gave me an option, so I of course took the less expensive route. Ive never had any problems with the replacement pipe, and I recommend their shop to anyone who will listen. Thanks again for the great work, great customer service, and most of all, the great ethics.

Steve and West Coast muffler do outstanding work, are super helpful, friendly and highly recommended. I brought a little old Honda Elite 80 exhaust/muffler to get repaired and they did a fantastic job, even cleaned and coated the unit with rust inhibiting paint! Looks brand new and saved me lots of $$!

Love this place! I have taken 4 Trucks to them for exhaust and brake work. Great service, very friendly and the quality is suburb. The welds are so much better then other places Ive been. All three trucks were show trucks and came out excellent. Thanks Steve and staff! Also very good prices for the work they do.

Steve is nice guy, great price and fast. Thx!

So my Saturn had a exhaust leak I thought. I took it to Certified Tire in Concord and left it. I got a call later fr,om them telling me that I had an exhaust leak at the manifold. I knew that so can you fix it? No they said, you gotta go to a muffler shop. Oh and by the way, its gonna be $62.50 for us to tell you that we cannot fix it. I took the car to Steve at West Coast. This cat used a stethoscope to find my exhaust leak! He then told me that he could not get to it now and had to order parts since it was a holiday weekend and gave me a accurate quote to fix it. He also said that I did not owe him ANYTHING since I did not fix it. There were tons of custom hot rods all over and the place reeked of So-Cal hot rod heaven. I will take it back to him next week. This cat was decent, shop was spotless and he had integrity.

I have used West Coast Muffler a couple of times now. They dueled my truck before. This time they added K&N CAI system. Both visits Steve provided excellent work and service.I grew up knowing the sign of a good automotive service business is that it is a busy business. West Coast Muffler is a busy business.

Steve is always very helpful and not just on exhaust systems.

Took my Fiesta ST to get a muffler delete and exhaust tip installed, they were super quick, great price, and my car sounds great now. Would definitely recommend.

Great service staff and work...I recommend fully...🤘🤘🤘

West Coast is wonderful. They essentially built my 67 Camaro with an LS2 drive-train and completing a great resto-mod. The car is featured in some of the photos (blue-white).Steve was great at managing the project and it moved quickly with the expert help at his disposal. The car is the best conversion Ive seen thus far - a joy to drive!You wont find a better or more honest person to deal with your needs.

Great place for all your car needs

Got American thundsr exhaust on my charger rt with cold air intake. I love the exhausts, very professional. Lind rocks she knows her stuff

I went in today to get my new catalytic converter installed. They let me use the part I bought and charged me a reasonable price. I was very happy with Steve and his service, I will be back soon!

I came in to get an exahaust valve on my explorer just to annoy the neighbors 😂 a couple months ago and they did an awesome job and I recently came in to get a cat and muffler on my mr2 and ive never herd it so quiet I LOVE IT!! 👍 And prices were descent not to expensive 👌

Great service, Excelent knowledge, helpful personel.

Been coming to Steves shop for a very long time. No bs shop very straight forward and definitely knows what there doing!

Had a Corsa Xtreme caback back exhaust installed on my 2015 mustang GT.Dropped it off before work, picked it up afterwards. Everything was perfect sounds AMAZING!

Hello i had a 1974 chevy 4x4 that my dad had since 1975 and it was just passed down tho family from my brother then to me .. anyways i took my truck to West Coast Mufflers to get a pipe fixed cause i had one blow though the mounding plate that bolts to header and Steve fixed and he it wont do it again .. i asked him how it did that and he who ever put those pipes on they didnt crimp it right.then a month or so later i had Steve put some used Flowmaters on it.. it had glass packs on it when my dad had it. and i dont like noise they did so i took them off and put flowmaters on it .. and hour or so later Steve said it was done ... boy it sound so much better. and ill take my cars and trucks back to Steve again.just 6 months ago my g/f has 64 chevy Impala and want him put some new pipes and flownaters on it and he (Steve) gave a price of $700 to $800 bucks. and ofcourse my g/f cant afford that. and i told my g/f i rather have West Coast Mufflers and Steve to put them on.. what did she tell me lol ... i cant afford it ugh! well werestill driving it with those old pipes and worn out glass packs. and darn car being a X-body car it hard to route pipes for it with lots of bends and turns and alit of it is thelabor to do it. so i might have just buy my own mufflers and pipes and just have Stevebend pipe make it fit. and i hope it just pay for his labor and time to do it..oh and ill rec other people to West Coast Mufflers :)again i was very impressed in Steve and his work. GREAT JOB!!thanks

Awesome job done on my 1950 Oldsmobile

Great service! Thanks Steve 😁

Best place to get it done right.

Great service...thank you, Steve!!

The right place to go, he will get it done right.

I didnt bring in a hot rod but rather our minivan. I had a broken pipe hanger and was expecting to pay $$$ for a fix. Upon putting the van on a lift for inspection, Steve tack welded the hanger back together for the most minimum of charges. I still had the rest of my lunch hour. Bravo Steve!

Nice shop......
