    ARH long tube headers long system for the 2005-2006 GTO features 304 stainless steel 1 3/4" primaries, 3" merge collectors, along with all the necessary hardware and gaskets for a bolt-on installation.

    The 2005-2006 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. JDP Motorsports suggest using the catted pipe as they cause very little restriction and they help to control emissions.

    Note: This system does not come with an x-pipe. Check out our X-PIPE OPTION GTO system here.
