Avoid getting ripped off and sub-quality work from the "big guys" and take your car here! I moved to the area not too long ago and finally had the occasion to need to find a new mechanic for a much-needed brake job. I called and made an appointment, but at then called to see if I could move it up a day and they had no problem working it out for me. The work was done quickly, with very high-quality parts, and was done honestly. In fact, I was going to get some additional work done and he said not to worry about it rather than just taking my money. read more

I needed some muffler/exhaust work done. Someone attempted to cut off my catalytic converter but I guess was spooked and only cut about a quarter the way through on one pipe. I took my car in to have them look at it. Ricardo pulled my car in looked it over and quoted a fair price. He then proceeded to do the work as I waited. Took about 15 minutes. Super pleased and will come back if I need this type of work done in the future. read more

He worked on my custom exhaust. Without having to set an appointment, I just showed up. Did it pretty quick and did a very good job with the welds and aligning the exhaust make sure it's perfect! I was able to be there and explain exactly how I wanted it done and there until it's finish. Will come back for my future exhaust projects! Nice people and shop is chill! read more

Our car had it's catalytic converter stolen. Our insurance company recommended Tri-Valley Muffler. Tri-valley Muffler not only had the most reasonable cost in the tri-valley area but the quality of their workmanship was excellent. And, very importantly, there were no issues with the CA certification of their catalytic converter work. They also installed a very cost-effective solution for deterring any future catalytic theft. read more

I took my 91 Sentra in because it was loud as hell. The exhaust pipe cracked and the muffler was shot. I asked them to make it quiet! They first fixed the exhaust pipe which helped a lot. They told me to come back later after they got the muffler in stock. I don't know what they did but the car is quiet as heck. Performance still there. I thought making it quiet would make it slower but it still performs just like it did when the car was loud. Very happy. read more

Carlos replaced the catalytic converter on my 2005 Prius after it was stolen. He also welded rebar directly onto the exhaust pipe and added additional rebar in order to block access to the catalytic converter, to help deter future thieves. Service was courteous and quick. Recommended. read more

Tri-Valley Muffler & Brake - New mufflers on my project Nissan 350z - Auto Repair Near Me - Dublin, California

Son gets an infinti G35 and has Carlos Y pipe the exhaust and go without a muffler. He is so super happy with the sound and performance. Me well I am thinking it should be quieter but what do I know. Carlos and Chavita did take my FJ cruiser and put in a magna flow muffler and add dual exhausts. Sounds and looks great. So nice to me and my family. I always joke with them and gave them both hugs to show them how much I appreciate their family business. I am MUY CHEAPO.....El CODO!! They understand and make me very happy. They also installed some spacers for the wheels I picked up. Gives the FJ presence and stability. They do great work and very friendly. My son brought his friend and now they are both waking all the people in San Ramon up every night!!! read more

Ricardo just replaced the catalytic converter on my 1999 Honda accord V6 EX. I work as a Fraud Investigator in the automotive industry. Ricardo is as honest as they come. Quality workmanship and no hidden charges. He finished it when promised as well. With all of the catalytic converter theft going on, you do NOT have to go to a dealer for a $3,000 cat replacement. Call Ricardo before you go anywhere and at least have him look at it. He saved me a bundle and its legal too. No funny business. It just passed smog. Nice guy, too. read more

These guys were extremely quick and efficient had a muffler delete done and my truck sounds great thanks fellas I'll def be back!!

Had 2 resonators swapped out on my car, work was quick and welds looked clean! Price was fair as well.

Just got the following message from the owner: Hey bitch Just wanted to say suck my Dick you bitch ... Looks like someone is still upset about his shoddy work. read more

I went in to get a quote about getting a muffler delete on my Lexus about a week ago. The price was good and I had planned on making an appointment to get it done later but they took me right in! As a female, a lot of the guys try to raise the prices, but these guys didn't! They were super friendly, did it super fast, and it sounds GREAT! I even made a comment about needing my breaks done and the guy told me how much it would probably cost and told me I can come in whenever. Definitely going back, cool people!! read more

They worked on my muffler for my car twice did a good job. I enjoyed their shop and they had fast service.

Ricardo is the best at brake and muffler repair. What is that brake dust on my wheels?? No it's to be snorted? Cocaine is sweet and gets you high as a cloud. But don't mess with Gallardo family, they have the fire power to leave you in the dust. read more

Called at 3pm today (a Friday) and asked if he could squeeze me in for a muffler and tip for my 2014 Silverado. He said "no pronlem, come by and I will help you." I called a few other people and they lauhed, which I totally understand, its Friday. These guys (Husband and wife ) put my truck on the rack and we discussed options and tips. They took their time and allowed me to peak once and a while, as I haven't ever had a good view of the bottom of my truck. Very professional and a good hardworking family vibe. Even worked with my budget. Going back when I decide to go bigger :-). Thaks you guys!!! Truck sounds awesome with no interior drone. Woohoo! read more

Had my 2016 392 Dodge Charger mid muffler delete done here, very reasonable prices and Ricardo is very knowledgeable. I have to say, I hear the roar in my car now when I cut loose on my way home. Second day writing this review and very pleased with the work. They also took there time to adjust my muffler's height, even though that was already slightly off from factory (Thank you!). They definitely do not mind talking to you and taking care of you. I wish I would have came in a week earlier, they did a mid muffler delete / new exhaust tips on a Dodge Demon... yeah that's right a Dodge Demon. Still haven't seen one on the road but yet they worked on one last week. I would recommend this place if you have any muffler work you like done. read more

I have a 2000 Lexus GS300 and I got a muffler & resonator delete then straight pipe and it sounds amazing I also bought a tip to go with it they had to do an s bend on the pipe because i wanted a single exhaust and everything fits perfect its not loud when i drive unless i floor the pedal and i dont even hear cabin drone overall its outstanding read more

This place is GREAT ... if you can find it. its not too hard... just... go down Golden Gate the shop is located down the second to last driveway on the left. It is a small business but man is the service wonderful! I called at 2pm on a Friday to get my brakes checked and possibly fixed.... because well... I've had my car worked on at many places before and needed it back for the weekend... I dropped my car off at 3 and then walked up and down Dublin Blvd to get some shopping done. By 3:30 I was called and given a VERY reasonable estimate over the phone. at 4:45 I received another call letting me know my car was ready for pick-up!! I was still in line at Target paying for my new shoes! So... I high-tailed it back to the shop where they apologized to ME for taking so long... I payed for the repairs and was on my way.. My brakes have never worked better and I will absolutely be calling them for my future car repair needs read more

I've been going to Tri-Valley Mufflers for about 6 or 7 years with some crazy custom exhaust jobs. They do amazing work and for a good price. Haven't been there in a few years, but I'm thinking about heading back for another round of exhaust on my 07 Silverado, and yes, they did the first round as well. Sorry no pictures of that truck yet because I haven't sold it. But you can check out the other pictures I've posted of the work they've done on my other trucks! read more

These guys are top of the line with their great service and value. I've brought three of my pick-up trucks here to get the muffler taken off and get the piping done just the way I like it. They are a family business and very nice and friendly. DEFINITELY COME HERE. THEY WILL NOT LET YOU DOWN. By far my favorite muffler shop in the bay area. I'll definitely be back with my next project!! read more
