We Specialize in Catalytic Converter Diagnosis and Replacement

Exhaust Repair Specialists

Lou’s Custom Exhaust Lynn Ma., on the Lynnway offers a wide range of automotive exhaust services at our auto repair shop just north of Boston. The exhaust system in your car or truck has progressed over time to become a combined safety and emission control system.

The exhaust system should be inspected regularly and repaired immediately at our service center if you notice any problems. The exhaust system’s very purpose is to protect a vehicle’s occupants from harmful engine gases by redirecting those gases away from the car to the outside air. The exhaust system also helps to ensure a quiet and peaceful experience by minimizing engine exhaust noises while driving in and around Boston. The catalytic converter is an exhaust system component that minimizes the amount of dangerous pollutants found in the engine exhaust. Other components of the exhaust system include oxygen sensors. These sensors monitor oxygen levels in the exhaust gases for the purpose of ensuring the overall efficiency of the catalytic converter and engine’s operation.

Various factors contribute to the wear and tear of your vehicle’s exhaust system, including your driving habits, Boston road conditions (salt, bumps, road spray), the type of vehicle, and the age of the exhaust system parts. Some warning signs that may indicate vehicle exhaust system problems would include loud rattling noises heard during vehicle start-up, acceleration, braking, and experiencing drowsiness while driving.
