A properly operating exhaust system ensures toxic exhaust gases do not enter your vehicle’s cabin while providing proper engine performance, assisting to maintain fuel efficiency, and reducing air pollution. As the exhaust system experiences wear and tear, auto exhaust repair is essential in maintaining proper emissions and engine performance. In addition, improper exhaust can result in overheating of the engine. Fifth Gear Automotive can provide the automotive service you require in our auto repair shops in Lewisville, TX.


The exhaust system begins at the engine in the exhaust manifolds which connect to the engine cylinder heads. The exhaust gases exit the engine into the exhaust manifold, traveling on through the oxygen sensors where they are analyzed, into the catalytic converter where they are broken down, and through the exhaust pipe into the muffler where the noise is reduced and finally exiting into the environment.

The Catalytic Converter

The catalytic converter is responsible for breaking down noxious gases from the engine’s exhaust. Driver’s often are unaware of a problem unless the car undergoes a routine emissions test, or when the component fails. Do not continue to drive a vehicle with a failing catalytic converter as serious damage can occur to the engine.

The signs of failure may include poor engine performance and an unusual odor in the vehicle’s cabin. The check engine light may come on in some cars when catalytic converter issues occur. A car that is overheating and shuts off is a common sign of  converter failure. The gases can not exhaust, causing the engine to overheat and preventing the car from running. When this occurs do not keep driving the car, have your vehicle towed to our auto repair shops in Lewisville, TX for catalytic converter replacement.

The Exhaust Pipe

The exhaust pipe directs exhaust gases from the engine and the cabin to be exhausted from the exhaust pipe. Holes, cracks and separated sections can result in exhaust gases entering the cabin, including deadly carbon monoxide. In addition, you should never allow pets, children or others to ride in the back of a pickup truck with a camper of any kind on it. An exhaust leak can result in the suffocation of occupants as the gas builds up inside the camper. Carbon monoxide replaces oxygen carried by the blood’s red blood cells, resulting in permanent brain damage or death from suffocation. When your car has an exhaust problem, do not take the risk, bring your vehicle in to Fifth Gear auto repair shops in Lewisville, TX today.

The majority of exhaust pipe issues is not recognized until the hole or crack becomes large enough for noisy exhaust or rattles to occur. Request an exhaust inspection when you bring your vehicle in for its annual maintenance. A louder exhaust noise is a common indication of exhaust pipe or muffler issues.
