Made of High Quality T304 Stainless Steel Material
The exhaust manifolds found in the 2005-2010 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.
The 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 2.2L/2.4L engines.
