What clients say about Big B Mufflers & Catalytic Converters in Lake Forest (CA)
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.
Did a magnaflow install on my dodge challenger and I couldn’t be happier great service and he worked fast and the exhaust couldn’t look or sound better . Would recommend
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 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.
I rarely give 5 star reviews. Not only was he knowledgeable, but his price was more than fair. Finished when promised and reached out to me as soon as he was done to let me know. And he was professional and friendly. Glad I researched other companies before I went there. Overall, a cut well above the rest
Owner is doing this job with his car , motorcycle hobby.I been there 2 days because of I bring wrong part for my two Prius car .He is really nice .He skillfully can fit catalytic converter cover from stolen thieves.Also the the most cheap price in Orange County.His dog is friendly too.Thanks Bro!!!!!
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!
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.
Took my 2022 Gli in. Brandon did an amazing job. Spent some time and really focused on getting the exhaust tips perfect! Really appreciate his attention to detail and quality work. Guys got a laser hand!
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 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.
Brandon's really awesome! He's straight to the point. He has good pricings for excellent welding. I come to the shop every so often with a small project and he's always doing the best deals. Extremely helpful on a tight budget. I would recommend him to anyone who I talked with oh, he is very trustworthy and honest.
Had to get a muffler put on my car and had no idea where to start.
Took my car here and Brandon was awesome about steering me in the direction and showing me where to buy the part, so I could come back once I received it for installation.
About a week later after I received the muffler, Brandon performed the install for a great price, in good-time, and with a smile!
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.
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!
