Brother John, I know we just met, but you're alright in my book. ? Not only is he very knowledgeable with over 40 years experience, but does quality work and doesn't mind having a great conversation while doing the job. Got exhaust work done on my 392 Durango SRT, and what began as a solemn rainy day, has turned out with a smile on my face after my visit to this shop. Thank you, John, and top marks across the board. I should've took a photo when I was under the truck but I forgot. Oops. MM delete with custom plumbing in its place, even fixed the stock exhaust divot from the original hardware; 100% happy with the results. Highly recommend any one else to bring their project here, whether it's a new whip or a one of a kind old school sleeper. This brother can handle it all. Price also on par with other shops that'll actually DO the work.

John’s shop has become my go to place for any and all car repairs for a few years now (several cars). While he is amazing mechanic on modern cars, he also truly has a talent on classics. Every time I visit, he’s got another beautiful classic car racked and being worked on. His prices are fair, his knowledge is top notch, and he’s friendly to boot. Definitely recommend making him your go to guy.

Randomly stopped in when I saw the sign for White Marsh Muffler & Brakes while searching for a shop to diagnose my recent exhaust leak. Walked in and met John the owner. Great guy. He graciously brought my car into the shop, diagnosed the problem and fixed it on the spot. I only expected him to diagnose the leak and give me a price to repair. While there we talked life as he and I were close in age. 2 1/2 hours later and the car completely repaired we parted. John is very knowledgeable and strongly recommended his shop for all repairs. Not just muffler and brakes.

John is the owner of White Marsh Muffler & Brakes. I recently brought my 1970 Mustang Convertible in for a broken exhaust hangar. He R/R the part in minutes, although we spoke for over an hour on vintage and classic cars while listening to great tunes. I wish I only knew what John has forgotten on "old" cars. He is worthy of 5+ stars.

John is the owner and operator of this fine establishment and knows how to take care of customers. Our catalytic converter was stolen, and it took a dealership almost four months to replace it. Unfortunately, it was stolen again on the day we went to pick it up. However, John saved the day and had it replaced within hours. He is very knowledgeable and a master in his field. I highly recommend him to anyone needing a new catalytic converter, especially since they keep getting stolen.Service: Exhaust

John was absolutely fantastic to work with - extremely knowledgeable, patient, and hard-working. He took the time to explain the mechanical issues in detail, spent hours researching to find a specific part needed on our older vehicle, and was extremely efficient with the assembly. HIGHLY recommend!

I had a custom exhaust installed on a 1973 Corvette at White Marsh Muffler and Brakes. It looks good and sounds great. I stopped in there today to see is John (the owner) , would know where I could a fuel line fitting that I could not find anywhere. I knew it had a couple of bad thread and could not stop a small gas drip that I wanted to stop. He looked at the fitting and agreed that there was bad threads, but also noticed something that I didn't. It also was a little distorted where the tubing went thru and that is where the drip was coming from. He looked in a box, found one and gave it to me. I am so glad he did, because I could not find one locally. I am my own Mechanic, but sometimes I run in to things I can't whip or understand. When I do I will take it right to him. He knows his stuff. He is more then a Muffler and Brake man. This car is 50 years old and I have had it for 30 years. I don't want to take it just anywhere. He is honest and sure can be trusted with his work. I found out about him from someone that has a Show Car that he put an exhaust on. He don't mind sharing he knows with you. I highly recommend him.
