Pontiac G8 GT American Racing Headers

Pontiac G8 GT owners wanting that GXP horsepower can have it by adding American Racing Headers' new G8 system. Like everything American Racing Headers builds, these new systems are made in the USA using the highest quality 304 stainless steel. Available with 1-3/4" or 1-7/8" primaries and merge collectors with scavenger spikes standard, ARH's G8 system guarantees outstanding performance with great fit and easy installation. Features include 3/8" thick stainless steel flanges with hand ported inlets and 200 cell metallic substrate cats. Recent dyno testing showed gains of 38 RWHP and 41RWTQ (before any tuning or cold air systems were installed).

Note: The degree to which long tube headers affects your system is so large that it requires a tune with installation.
