Walked in to ask questions about exhaust recommendations for my 2021 Silverado. Ended up with custom work done in an Hour and a half. Highly recommend this shop. Super professional and very knowledgeable!!

I set an appointment to drop my truck off to have a new performance muffler and pipe done they had the truck done the same day within a few hours and even diagnosed and fixed my no tail light issue while doing the exhaust work. I'm happy with the sound, work, price, and turn around time. I Highly recommend American muffler and Auto Repair for exhaust work or auto diagnosis/repair

Came in for a quick repair when I sheared a bolt off in my crossmember. They got me in on short notice, fixed the issue promptly, and did it all at an extremely reasonable price. Very professional and affordable, I'd highly recommend.
