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.
