Took my 2002 Camaro SS here to have the y pipe re-bent for more clearance. Upon getting it back, I experienced a horrible vibration when accelerating. I called them to explain and they said "that's just how old cars feel". This is coming from one of their staff that drove it for 2 minutes. I've owned the car for years, I know how it feels. Turns out they pointed the exhaust clamp directly at the driveshaft so it was just eating away at it. I told them and they didn't care in the slightest. Also, their welds look like they were done by a 3rd grader. Stay far away from this place read more

Very friendly and helpful. I got my brakes and rotors replaced in a couple of hours. Great service, I'll definitely use them again! read more

I have had 2 cars done "COMPLETE EXHAUST"at this place in an attempt to fraternize with the local businesses since I live in the neighborhood. However I was severely over charged both times. Went back to have tailpipes installed and they wanted to charge me over $500.00 dollars W.T.F. Not to mention there award winning personalities! I don't like or get off on slandering small businesses but when you are intentionally price gouging hard working folkes , I could care less about you. There are to many reputable muffler shops that give you a fair price for what they do, especially on muscle cars, I definitely recommend Livermore Muffler, Antioch Muffler, Minute muffler in (Oakland) they do Awesome work. Oakley muffler just lost not only me as a customer but everyone I know in the muscle car movement. STOP ROBBING PEOPLE, we all hurting out here. read more

Nothing towards the business, I live right next to them and their security alarm goes off constantly keeping the neighborhood up. Wonder if anyone is actually breaking in lol read more

Great shop! Roberto assessed my situation and did a great job on my muffler-delete. Everything lined up perfectly and sounds amazing. I will definitely refer friends and family to this local spot! Thanks again for taking good care of my 1LE Camaro. read more

Oakley Mufflers - Auto Parts & Supplies Near Me - Brentwood, California

Fast, affordable, friendly, and professional! Can't be more happy with the work performed.

My son's car needed repair but I am located in Southern California. Kind lady named Alma assisted me in getting the car fixed from this location. Really made the experience pleasant. Kudos to them and her. I highly recommend this business. Efficient and professional. read more

Had my truck exhaust redone today. Very good work and reasonable price. So happy I found this place!

Called the business at 7:50a and talked with John. He invited me to look at all the Flowmaster series he has in stock. John is very knowledgeable and helpful when it comes to narrowing down your selection. We agreed on installing the Super 40 series on my 2011 Tahoe. Since I will be mostly driving this with my kids, I didn't want it to be super loud. The job was done in 1.5 hours. John shared that he has been in the industry for 35 years and decided to go business for himself 28 years ago. He even showed me the original "For Lease" sign he had when he got started. I highly recommend this business. Honest and trustworthy people are rare now a days. read more

After I drove over a carjack, my car was severely damaged. After all was done, fixing the exhaust was my last stop. I went by Brentwood muffler and repair to check it out, and they sent me to Oakley muffler and repair, their sister shop. I explained to them what has happened and need to see if my exhaust is damaged. The put the car on the lift and explained to me that the muffler was not damaged during the accident. I offered to pay for putting the car on the lift and they insisted that it's part of their customer service. The car did not need to be fixed at all. So, they made no money from me. Even after considering that, they still didn't charge me a dime. Good people and a great shop. If I ever need any mufflers in the future, I know where I'm going. You're customer service has won me over. Bravo guys! read more

I took my 89 Chevy pick up truck it needed brake work. I've been to a few other shops no one could figure it out. Didn't want to keep spending money on it told Javier and Roberto what I did. They figured out the problem and fixed it. My brakes have never worked that good. I will definitely go back when my other vehicles need work done they did a great job. Thank you. read more

Roberto did a good job. Well detailed and made Sure that everything goes to what I was expecting when he welded my exhaust. read more

Excellent place of business !! I've used this Good place since 2010 . And Recommend Many people ever since . Always Honest , Fare and sometimes Closed on Saturday read more

Wish I could give zero stars. My advice is to stay away! Took it in to get an alignment and for an exhaust noise. Charged $225. Muffler noise still there and they messed up the allignment royally. Tires were visibly pointed in opposite directions making steering dangerous and letting my ha mileage to about 65% of what it was before I took it in. Not even sure what kind of damage this caused to my drivetrain. To fix the exhaust noise they did some "welding". The weld quality was about what I'd expect from someone picking up the torch for the first time. Needless to say the noise is as bad, if not worse, than it was before. Complete waste of time and money. read more

Took two of my cars here for some exhaust work...The staff is very friendly, knowledgeable and does clean work. They are on the more expensive end though. We recently moved so my regular muffler guy is a lot farther than I wanted to drive...his prices are definitely cheaper with equivalent work quality. Overall, I am happy with their work & service so I guess you get what you pay for...for me I was also paying for convenience. read more

I actually went to this place to get flowmasters put on my 91 Bronco back in 2000. I loved that they squeezed me in without an appointment despite being booked for the day. This stood out to me and I've always recommended them to others since. Today I dropped off my 88 Ford F-250 to get flowmasters put on. Even though it's been years since I been there I was still confident I'd be getting the same quality work. A few hours later my truck was making that trademark rumbling sound that flowmasters is known for. While under my truck Roberto pointed out a couple of things that he recommended be replaced. He showed me and explained to me how the parts were failing. I appreciated how he took the time to explain things to me and give me his recommendations. I love my truck and I will definitely trust Oakley Muffler with it. read more

These guys are great, they installed flowmasters on my mustang at a great price, fast and professional, now my mustang sounds like ot should!! read more

We have been using Oakley Muffler & their sister company Brentwood Muffler & Auto for several years, but recently it seems we've had to take one vehicle after another. They have always been honest and we usually end up out of the shop for less money than we anticipated having to spend. Just this week their call made our day when we brought in a fleet truck that wouldn't go into park and we assumed needed a whole new steering column or had a bad transmission. Upon their inspection, it was a loose bolt that they were able to fix within an hours time. They got us back on the road and for barely over $100 our day was saved. read more

I've been taking my cars here for 17 years. The service and work are great. They do good work and have never felt like they are trying to pull a fast one on me. No complaints about the work they've done. Once they even came to where my car was broken down in town and fixed it enough to drive to their shop and then finished fixing it. read more

Best place for Performance Exhaust installation and welding. Robert is an expert for Mandrel bends of exhaust pipes.

Needed my exhaust moved. They got me in the next day and knocked it out in less than an hour. Sounds great and doesn't hang low anymore.

This is my second time coming to oakley muffler and the results are just as good as the last. Had an oem muffler put back on my 03 Volkswagen the first time. This time I needed an exhaust hanger and bent rear pipe replaced on my 07 ram. The work looks great, nice staff, and it only took about an hour or so on a busy Wednesday. read more

Roberto has done 3 of my cars now. Always gets the job done right and takes his time on measurements for an even finished look. They have a good inventory of tips and mufflers at the shop. read more

Went in for a cat converter got my car back sounding worse. Stay away from shops like this. They do not value their customers or guarantee their work. They seem careless. And the lady at the front desk is terrible with communication read more

Wow!! Found this place with no reviews. And wasn't sure about it. But I came and talk to very friendly people and they gave me a great deal on my muffler installation. The best I can do in return, is let everyone know. He told me better to weld it. So nothing raddled. Great idea! Gonna spread the word on Facebook too. Came back and his brother?? Was trying to over charge me. Went to bounny muffler shop in Oakland and they charged me half the cost read more

Javier and his team knocked another one out of the park. Roberto installed the cat-back system on my 328. What attention to detail!! Roberto made every effort to make the symmetry of the install perfect. Job well done! Thanks again!! I'll be back, for sure. read more

Javier and his crew are some of the best in the business. I came in very early because they said they could do my trucks exhaust without an appointment. As soon as they opened he met me at my truck and pulled it right in. Took my single out Silverado exhaust to dual with chrome rolled tips and a Flowmaster 40 series. I was on the fence between the 40 and 10 series so the mechanic took each muffler and held it to my trucks cut exhaust underneath with pipe out the back to hear difference. I called several different shops only to find that of course they had the best price. Javier has done several of my other cars and each job has been awesome. Clean welds and pipes lined up evenly. They treat each car like it's theirs so you won't be disappointed. Took 20 minutes just making sure my exhaust was even... true attention to detail. This is my go to for any exhaust work... not to mention they do a lot of auto repair too... ask for Javier he will take care of you..he is the owner and a great guy read more

I've taken 2 of my cars here in the past for both exhaust work and alignments, and this shop has always done amazing work and I will give them that. They are the only shop out of many that I have went to that will do alignments on my lowered cars, and they always do an awesome job with prices in the past that used to be fair. Their exhaust work is great too and their welds are always great and not rushed. As of today (June 8th 2023) I will no longer be bringing my car here for exhaust work. I don't know what exactly happened to the low prices I used to pay but today was mind blowing. For a magnaflow muffler which is listed at 115$ on magnaflows website (I was charged 175$) and a resonator delete, I expected to pay no more than 300$ as that's what I'm used to being quoted from my previous times coming here, considering labor and the piping, but boy was I wrong. Upon getting my quote today I was hit with a whopping 570$ quote for an exhaust job that took an hour. WHAT! I get that everything has gone up in price lately and parts are getting harder to find but.... come on. I felt like I was robbed. Yeah the work they did on my car today was pretty good and the welds are smooth but for 570$ I could've taken myself somewhere else for cheaper with the same result. Their sister shop that is right down the street is no better because while they were working on my car I walked down there to see what their quote would be and they said 800$, I don't know about you guys but that's a little ridiculous. Y'all lost my business. read more

Went to these guys for years for my projects. Recently came by for something small but turned into a bigger issue afterwards. They didn't disconnect my battery when welding and now my ecu is fried and car is in limp mode. Spent $500 on sensors that didn't need replacing and another $500 or more for a new ecu and key. I admit everyone makes mistakes but a $40 weld turned into a money pit. Took me over a week to figure out the issue. read more

These guys are awesome! The dealer price for an air shock on my BMW 740e was over $2800 just for the part and I couln't get it done anytime soon. They put one on and programmed it for half the cost and same day service once the part arrived a few days later. Not the first time I have used them and not the last. Happy to get great service locally. read more

Took my van for an alignment. Was quoted $586 parts and labor Including $50.00 for tire rotation. 266.00 for inner and outer rods. Up charge the parts 300% at least. Did let them do the work. Never taking my vehicle there ever. read more

Can't say enough about Mario at Oakley Mufflers. Brought in my S2000 for an alignment after replacing suspension components. He specializes in S2000s and was able to point out an issue I couldn't find previously and got me taken care of. These guys are respectful and great at what they do. Huge thanks to Mario! read more
