ARH long tube headers long system for the 2004-2006 Pontiac GTO features 304 stainless steel 1 7/8" primaries, 3" merge collectors, and x-pipe along with all the necessary hardware and gaskets for a bolt-on installation.
The 2004-2006 GTO American Racing Headers long systems were designed to bolt-on to your factory axle-back or any aftermarket axle-back. Some modification may be required. The American Racing headers are offered with or without converters. Catted x-pipes cause very little restriction and they help to control emissions.
