American Racing Headers
Not to be out done, ARH's GTO systems are here to make a statement. Manufactured in 304 S/S, these headers are available with 1-3/4" or 1-7/8"primaries. Merge collectors with scavenger spikes are standard along with our bullet proof high flow metallic substrate cats. Systems are direct bolt-in for all 2004 - 2006 models. Expect outstanding performance gains throughout the rpm range and second to none fit and finish
