Would give 6 stars if possible.
I had a resonator deleted from my Civic Type R.
Brandon delivered quality work at a great price, and provided execellent customer service.
Also wanted to add that his shop was super clean and organized!Feb 06, 2026 -
Nice guy and fair price. Sent me photos when completed. He also has a puppy which is a plus. Would go here again without hesitation.

Stopped by for a resonator delete on the family wagon and Brandon was cool enough to squeeze me in (but he is genuinely always busy, so I recommend scheduling an appointment). He also patched up a crack in my exhaust that I was unaware of and had me on my way. So grateful I found a skilled fabricator who knows his stuff, honest & affordable. That’s hard to find these days. He also does mobile welding which is a bonus. Anything you want done, with quality at a reasonable price, I highly recommend giving him a call or shooting him a text.

Went to replace an oxygen sensor that was throwing a code and it fell right off the exhaust pipe. The old attachment point had a failed weld. Found Brandon's shop online and gave him a call. He went out of his way to diagnose the issue and help us out for a reasonable price. This guy knows his stuff and went above and beyond to get us all squared away again. Coolest guy, would recommend him for any muffler or exhaust needs. 5 stars all the way! Thanks, Brandon!

Replaced my front and rear catalytic converters to meet California Smog standards. Appointment was scheduled over text which was nice and convenient. He did great work at a super fair price. Then, he helped me out with an odd problem I had with seized license plate bolts.
Super kind, professional, and clearly loves his craft.Nov 13, 2025 -
Great shop and overall experience. I could tell that Brandon (the shop owner) truly cares about his craft, and it shows in the finished product. Booking is easy and the pricing was excellent. I highly recommend this shop for any of your exhaust/muffler needs.

Had my exhaust installed here and couldn’t be happier. Brandon’s work is super clean, the welds look great, and he clearly knows what he’s doing. Fast, professional, and fair pricing—definitely recommend if you want it done right.

I challenge you to find a better person to support. And as a bonus you get what is definitely the best quality of work as well as the best experience. Just look at the lineup of awards. Resonator delete and x-pipe install. Also had magnaflow mufflers installed on a separate vehicle.

I’ve had a great experience both times I’ve been to Big B Mufflers. Brandon is easy to talk to and really takes the time to do the job right. The first time, he helped me out on a Saturday by welding an exhaust hanger—super appreciative he was available on the weekend. I just came back today to get an aftermarket muffler installed, and once again he did exactly what I asked, even though someone else had worked on the car before. The pricing was fair, he didn’t overcharge me for the wait time, and the work was solid. Definitely recommend if you’re looking for honest service and quality work.

I can’t recommend Brandon enough at Big B’s. Probably the most down to earth, friendly, and honest mechanic I’ve ever met. Great vibes through the entire process. He helped me diagnose and resolve the rattling coming from my dodge chargers muffler. I waited about 30 minutes, he did his work, and I was out of there. Will be coming back for all future exhaust and muffler needs for sure.

Wow. He is FANTASTIC! I've been a long time Collins Muffler customer because I live in Mission viejo. But they were busy this time, so I looked around. This place already had great reviews, so why not? Not only did he accommodate me right away, but his work is fantastic and HALF the price of Collins. He had to cut and fit a DINAN exhaust on my M6. Not straight forward, but easy work for him! Worth the drive!

I cannot say enough great things about Brandon @ Big B Mufflers. I am very picky about where I bring my '56 Nomad for work and I am so glad I went to Brandon. He was thoughtful about giving me advice, did top notch work and charged me a very fair rate. I will only use Brandon and Big B from now on for all of my exhaust needs!

I typically never leave reviews. However, Brandon deserves every bit of credit for his phenomenal work. There was a bit of confusion in relation to the scheduled date, he had me down for Thursday morning but I thought it was scheduled for Wednesday morning. With that being said, I came Wednesday morning, once he told me he had me down for Thursday morning I felt very bad and apologized for the miscommunication/confusion on my end and told him that I would be back Thursday morning. After discussing things with Brandon, he asked me for my number and said that he’d give me a call back when he was done with the car he already had been working on. 30 minutes later, I get a call from Brandon telling me that he finished the car and to swing on by. Once again, huge thanks for squeezing me into the schedule at such short notice. Brandon has a phenomenal work ethic, he's talented, polite, honest, and very knowledgeable.

Today, I had my exhaust pipe replaced at a Big B Mufflers & Catalytic Converters, and the experience was excellent. The owner, Brandon, is very professional and sincere, providing extremely useful advice. The shop is neat and well-organized, with thoughtful design that makes you feel at ease. His welding skills are impeccable, and the workmanship is top-notch. Even his dog, Danzig, is friendly and adorable! Overall, this is a trustworthy place, and I highly recommend it.

The owner (Brandon) was a very cordial, polite and professional guy. I needed a new tailpipe welded onto my car, and he was nothing but great throughout the process. The job was done in a matter of hours, and he was very reasonably priced. Coming back when I do an aftermarket muffler for sure.

Great experience with Brandon. I’ve taken two sporty cars to him for exhaust work. Most recent was to install a custom exhaust for my e46 m3 made by another shop. Fitment was off, rubbing heat shield and subframe, and making matters worse, I didn’t give him all the correct parts for the install!
Brandon was super cool and professional about it, and even texted me pics showing where it was rubbing, asking if I wanted to continue the install.
I told him to just continue and I would deal with it. He was able to get it installed perfectly, taking the time to even replace worn/rusty bolts and incorrect V band with a correct one. I will continue to take my vehicles to him, and recommend anyone to go to him, as well. Thanks, Brandon!Mar 28, 2023 -
The best service and experience I’ve had in a very long time. The man keeps a well cleaned and organized shop which speaks volumes by itself. It’s a classic old school muffler shop which is sadly a dying breed nowadays. Anyways went to Brandon because an exhaust system I purchased didn’t fit exactly right, embarrassing actually lol, and after getting nowhere with the manufacturer just decided to seek out someone with the talent and willingness to make everything look and fit the way I wanted.
All expectations were exceeded on fitment, weld quality and pricing. Welds are thick , clean and very controlled. He’s straight to the point, no BS and genuinely wanted to get the job done.
Thanks again for taking on the task and spending the time to work on my car.Mar 04, 2023 -
Thank you for taking the time to work on my car! I highly recommend Brandon's work. He takes his time to communicate and coordinate with what you want. What I initially wanted was unable to be done due to the differences in muffler design but he was able to make the tip install work on my stock system. The work is great!

Brandon, the owner provides fast and excellent service. Had him install a catalytic converter shield. Great job! Highly recommend this shop!

First impressions were great. Then it was about 3 months of run around and excuses. Got tired of constantly having to follow up and ask when we could get a deposit down and get parts ordered. In the end we never heard back. Sadly, just can't recommend, seems like a flake. Went to Collins muffler & hitch on Tuesday, ordered parts, brought the car in for a custom full exhaust on Wednesday at noon, had the car back by 3:45.

Brandon was professional and courteous during scheduling and gave me a competitive estimate. His workmanship is stellar and I am quite pleased with his work, timeline and also purchased a custom helmet hanger for my motorcycle helmet. Clean shop, reliable service and excellent work! I had a new dynomax muffler and resonator installed on my F150 with precision craftsmanship and it performs and sounds amazing!
Highly recommended
ThanksAug 18, 2022 -
Brandon fixed my exhaust fitment. I'm very happy with how experienced he was and how clean he did the job with little bit of shaving on the diffuser that is not noticeable at all and overall I will come back when I need exhaust work!! It took him less than 10 minute

Brandon, took his time and did a great job installing dual exhaust on my truck! If you have a vehicle that you care about and you want the job done right, Big B Mufflers is the place to go.

I had an exhaust leak. Brandon worked with me, very patient and knowledgeable. Great price and he has a beautiful shop dog named Danzig. Worked on my Land Rover despite it being difficult without “huffing and puffing”. Never gave off that over worked underpaid, making the customer feel guilty for bringing in a hard project employee that you normally find at an auto place. Very professional. Kept me informed as to what may happen gave me the choice to move foreword. Didn’t just slip me a bill, very responsible pricing. Not to mention had to be one of the cleanest shops out there. Very impressed. Highly recommend.

They replaced the mufflers on both my Jeeps. Each time the Jeep was on the lift within a half hour of calling and they knocked out the replacement in about 30 mins. Great work at a great price!

Needed my rock sliders to be welded on to frame. Checked out a few other places but Brandon was the only person that knew what I was talking about.
The welding was excellent. I will definitely come back when I do my mufflers.Jul 11, 2017 -
Awesome Place! Took my 77 Corvette there to add some Flowmaster Mufflers and Bring it to life. Could not be happier with the work and love the new growl from the mufflers. Called in advance and was told when they could fit me in and they started work right on time. A++ Highly Recommended.

Brought my Audi in there for a muffler delete and he had me in an out in less than an hour. Such a cool guy, he even told me about the etnies skate park down the street. I just moved here so I didnt know many good places to skate. Brian, I believe his name was is a very genuine guy. Highly reccomend!
