SS/RED-LINE 2.0 STAINLESS STEEL HEADER+DOWNPIPE EXHAUST 05-07 CHEVY COBALT/ION

 

ITEM SKU: KOS-HDS-CB05-20L+DP

 

The exhaust manifolds found in the 2005-2007 Chevy Cobalt, HHR and Saturn Ion were designed to combine the exhaust gasses from each of the cylinders quickly with a manifold that was cost effective to produce. Our 4-1 off-road racing headers are designed to allow the exhaust gasses to flow more freely from each cylinder and combine in a more efficient manner. Tubing has been optimized for the 2.0L engine. This creates a reduction in cylinder backpressure and improved exhaust gas velocity. These improvements free up lost horsepower and torque. An added benefit is a more performance oriented exhaust sound.
