Q: What is muffler exhaust system?

A: A muffler is the exhaust system of an engine, designed to reduce emissions and noise. In the case of a vehicle, it is usually located underneath the car at the rear, though freighter trucks often use a vertically mounted system behind the cab.

Q: What is exhaust service?

A: Exhaust Service. The exhaust system is attached to the car by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines. Finally, we end at the tailpipe. This is the final outlet for the exhaust.
