Fits all 2009-12 Colorado and Canyon trucks with the V8 engine. Designed to fit the 4x4 trucks but also fits the 2wd trucks. The strut tower is close on the 2wd and sometimes needs a dent in one primary tube for clearance. Due to the way GM did
the exhaust, these headers will require you to have an exhaust shop
connect your cat-back to the headers.
