Your Chevy Trailblazer Exhaust System is more than just a tailpipe. Today's high-tech automotive exhaust is a highly sophisticated waste-gas disposal and monitoring system with several components that not only reduce toxic emissions, but fuel consumption as well. When hot gases exit through the outlet port, they go into a part of your exhaust manifold - or "header" - known as the "collector." These gases are literally collected here before they pass on to the catalytic converter.

This is a marvel of engineering that breaks the molecular bonds of deadly carbon monoxide and nitrous oxide, turning them into relatively innocuous CO2, nitrogen and water vapor. To do this, it uses a "catalyst" consisting of a ceramic honeycomb coated with a compound of platinum and palladium.

Next, on its way to the muffler, these converted waste gases pass through an oxygen sensor, which analyzes the exhaust for oxygen content. Based on this data, it sends an electronic signal to the fuel injectors, signaling them to adjust the fuel mixture going into the intake.

Finally, there is a muffler, which dampens the racket of thousands of tiny explosions by bouncing the sound waves back against themselves, effectively canceling them out. Since your Chevy Trailblazer Exhaust System is located primarily underneath the vehicle, it is subject to extraordinary wear and tear from road salts to concrete curbs and everything in between. When your muffler rusts through, or your catalytic converter gets clogged, you can count on us to have the lowest prices on any component you may need for your Chevy Trailblazer Exhaust System.Find out for yourself why people who love cars love our online store!
