For Pontiac G8 GT owners who want that GXP horsepower - why wait? You
can have it right now by adding American Racing Headers' G8 system.
Like everything ARH builds, these new systems are made here 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 a
great fit and a very easy installation. Other features include 3/8"
thick stainless steel flanges with hand ported inlets and 200 cell
metallic substrate cats. Recent testing on a Mustang dyno showed gains
of 38 rear wheel horsepower and 41 ft-lbs of torque (before the tune
and Cold Air were installed!).
