Exhaust FAQs
Yes. We can often replace only the damaged section (such as a pipe, flange, or muffler) rather than the entire system — saving you time and money.
The muffler reduces noise, while the catalytic converter reduces emissions. Both are key parts of your exhaust system and must function properly for your car to run efficiently and pass emissions testing.
Most mufflers last 5 to 7 years, depending on climate and road conditions. Vehicles driven in New England often see shorter lifespans due to road salt and moisture exposure.
Yes. Exhaust leaks can let carbon monoxide enter the cabin and reduce engine performance. If you hear a new noise or smell fumes, schedule an inspection immediately
Rust, cracks, and worn muffler baffles are the most common causes. Over time, road salt and moisture eat away at pipes and mufflers, leading to small holes that cause leaks and noise.

Excellent Hassle Free Service ⭐️⭐️⭐️⭐️⭐️Posted on GoogleChristopher R13 days agoStopped in for emissions testing. Clean space. Friendly staff. Exceeded expectations on turnaround timePosted on GoogleElizabeth R14 days agoI had a fabulous first visit and will be returning for all future repairs/maintenance! My car was starting sluggishly and had a vibration when braking. I called Mike's and they were able to get me in the following day. My service advisor, Lou, was very friendly and informative. He explained everything going on with my car and answered every question I had. They found play in my Tie Rods which is a huge safety issue but I had no idea as the play develops slowly and I was used to driving with the loose feeling. As the repairs were going to take a few days, Lou coordinated a Lyft ride for me to the shop so I could pick up one of their loaner cars. I appreciated this immensely as it allowed me to go to work/meetings without interruption. When I picked up my car, the steering wheel and my brake pedal are nice and firm, they feel like brand new! Thank you all for your kindness and dedicated work. See you next time!Posted on GoogleVictor P16 days agoI've been going to Mikes Auto for years. I always trust their advice and maintenance suggestions. Great service, great prices and great communication.Posted on GoogleDre N23 days agoMy A/C started blowing warm air and Honda quoted me $3800 to repair the condenser, A/C lines, O-rings, and recharge. I spoke to Trent and he advised me to bring my Honda Pilot in for him to asses and he was honest and thorough. Come to find out the A/C lines were fine and I was able to get my A/C fixed for $1500 and a 3 year/36,000 mile warranty thanks to Mike's Auto Repair. Will definitely be coming back for all my future repairs, great staff and service!Posted on GoogleJim K34 days agoWhenever I call for an appointment for an oil change they were always there to serve us.
