Muffler and exhaust repair.

At Fast Lane Auto, our ASE-certified technicians repair exhaust systems to boost engine performance, reduce noise, and ensure environmental compliance. We service mufflers, catalytic converters, pipes, and hangers, fixing leaks, clogs, or rust that disrupt emissions and amplify sound. In Massachusetts, a functioning exhaust is mandatory for passing state emissions testing under M.G.L. Chapter 90, Section 7A, part of the annual inspection process, and we guarantee your system meets these strict standards. Using durable, OEM-quality parts, we weld, replace, or patch components with precision, followed by a thorough pressure test to confirm no leaks remain. Our expertise ensures quieter operation and cleaner exhaust output. Whether it’s a rattling muffler or a failed emissions test, we’ve got you covered. Visit us at 27 Maplewood Ave, Gloucester, MA, for expert exhaust service that keeps you legal and serene—book your appointment now!
