Exhaust Systems

Your exhaust system is more than a muffler. Our team of technicians understands the intricacies of the system and offers top-notch exhaust repair and replacement services.

Your vehicle’s exhaust system is more than a muffler. It is a series of pipes that run under the vehicle, connected to the muffler and catalytic converter. The main function of the exhaust system is to control noise while funneling exhaust fumes away from the engine.


A vehicle’s exhaust system routes waste gasses from the engine to the rear of the vehicle. This is where gasses are discharged into the atmosphere. However, since exhaust gasses contain dangerous substances like carbon monoxide, the system also converts these pollutants into less harmful byproducts, reduces engine noise, and directs the gas so they can be used to heat air and fuel before traveling to the cylinders.


The vehicle’s exhaust system is an integral component of providing just the right amount of backpressure to the engine. This pressure helps improve fuel burning efficiency that increases the vehicle’s performance level. So as you can see, having a well performing exhaust system is not only good for the environment, but benefits your driving experience!
