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.

My 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 K13 days agoWhenever I call for an appointment for an oil change they were always there to serve us. If I needed a ride home I was able to get a ride home. I wouldn't go to any other auto mechanic then Mike's Auto.Posted on GoogleHalo A14 days agoGenuinely loved my experience initially went in for emission testing and the prompt service along with the technician being so pleasant convinced me that this is where I need to bring my vehicle . I had multiple problems with my vehicle and was kinda worried having it on the road but now OMG it’s the sweetest ride ever , it cost a pretty penny but it was worth it .10/10Posted on GoogleCarlos M28 days agoI went for an emission test. It was a walk in, only 30 minutes before closing, and yet they helped me with a smile. Service was fast and professional. Very clean place, even their bathroom was spotless!Posted on GoogleSpatty D40 days agoAppreciate that they are willing to work with you to save on costs.Posted on GoogleRobert P43 days agoI’ve been a customer of Mike’s for years. One car is 26 years old and the other is 12 so they must be doing something right.Posted on GoogleJoan S50 days agoThey thoroughly checked my car. And fixed everything. Very fair prices. Excellent job. Mikes Auto is the best. I've been burnt by other companies. But they are honest. Tell me everything i need b4 they do anything. They go above and beyond. This is the only place I will have my car worked on. They're all very kind and friendly.Posted on GoogleEm M50 days agoI can't say enough good things about this shop. I have brought my 4runner into them a few times. They just repaired my transmission lines by fabricating them, themselves. That says a lot about the effort they are willing to put in. As a car girl, myself i know those lines can be a royal pain! These guys are very honest and trustworthy. They don't treat me like a dummy being a woman as other places have tried to do to me in the past. They are very efficient and fair. I feel very confident with my vehicle in their hands. I will not go anywhere else for future work that may need to be done. I highly recommend them, always! Thank you to the wonderful team for getting my baby fixed timely! Appreciate all of you and the quality work you do.Posted on GoogleErika M51 days agoMike’s Auto is the only place I’ll bring my vehicle. I can’t recommend them enough! Colby was amazing. Not only did he save me nearly $15,000, but he also arranged and paid for Lyfts to and from my house without charging me a single cent. I recently brought my car in because the RPMs were spiking on the highway, and I also needed an oil change. They paid for a Lyft to take me home while they inspected the vehicle. After diagnosing the issue, Colby informed me that my powertrain was still under warranty and explained that the dealership would fix the problem and even perform the oil change at no cost. They easily could have completed the oil change I originally requested and charged me for it, but instead they were completely honest and pointed me in the right direction. Even though they didn’t charge me for anything, Colby still arranged and paid for another Lyft to bring me back to the shop. Their customer service is outstanding, and they’re truly an honest business that puts their customers first. If you’re looking for a trustworthy mechanic, Mike’s Auto is the place to go.Posted on GoogleJohn S55 days agoThree dealers failed to properly diagnose a fuel pump and fuel pressure sensor issue. Then i met Colby at Mikes Auto . Colby said his repair shop was better then the rest . Well he was right . He worked with my warranty company diagnosed and fixed issue service lights are off . I recomnend Mikes to anyone
