Product Description

This Dorman Exhaust Manifold is built for Chevrolet Trailblazers from 2002, 2003, 2004 and 2005. The Exhaust Manifold collects gases combusted in the motor and disperses them using your exhaust pipe. High-end Exhaust Manifolds incorporate primary tubes tuned to the exhaust pulse to accelerate the velocity of the exhaust, boosting engine horsepower. One of the critical components of your vehicle's exhaust system is the Exhaust Manifold, which removes all exhaust vapors from the engine's cylinders then sends the vapors via your exhaust system. High-performance manifolds can increase your vehicle's horsepower by reducing back pressure and augmenting the engine's volumetric effectiveness. If the Exhaust Manifold is deficient, the car will not pass emissions tests and may let unsafe exhaust vapors into the inside of the car. Chevrolet Trailblazers from 2002, 2003, 2004 and 2005 are compatible with this Exhaust Manifold. Other vehicles may not be compatible, and this Exhaust Manifold is not intended to be installed in those vehicles.
