Today's modern, high-tech Scion TC Exhaust System is nothing like the one on your grandfather's LaSalle or Hudson. The exhaust system of today is a complex collection of mechanical and electronic parts designed to work with the fuel and intake system in order to maximize power while minimizing fuel consumption - and keeping exhaust gases free of toxic pollutants. It all starts with the "header," or exhaust manifold, which collects the exhaust straight out of the cylinder.

While in the catalytic converter, the deadly waste products of internal combustion - carbon monoxide and nitrous oxide - are transformed into relatively innocuous CO2 and water vapor by breaking chemical bonds and recombining them at the atomic level. Next, the oxygen sensor tests the waste gases for the amount of oxygen present.

Based on this analysis, it sends an electronic signal to the fuel injectors, which then adjust the fuel mixture for the current driving conditions. The muffler then literally "muffles" the explosions of gas burning in the cylinders by bouncing these sound waves against each other in a special acoustic chamber, causing them to cancel each other out. Finally, this exhaust gas exits out the "tip," or tailpipe. For extra performance, you might consider adding any number of accessories to your Scion TC Exhaust System. An X-Pipe improves power by allowing exhaust gases to exit the cylinders faster and more efficiently, while custom headers aid this process at the point of exit. Because of their location on the underside of the car, most Scion TC Exhaust System components are subject to harsh conditions.Inspect these elements periodically, and when its time for repairs, count on us for generous discount prices on all your Scion parts and accessories.
