Exhaust Header 08-09 Pontiac G8 1 3.4 in Primary 2.50 in Collector Long Tube Full Length Hardware Incl Polished 304 Stainless Steel Pypes Exhaust

We put these on our Pro-Charged G8 GT and with only 6 lb of boost hit over 500 hp at the wheels. The headers are a bolt on and one of the easiest LT headers you'll ever install. On the back side, they bolt right up to your factory mid-pipe or a new Pypes H-Box or X-Box.

With this combination, you will not have catalytic converters so check with your state's laws in this regard. We can tell you that even with the headers installed, the catalytic converters removed and a Pypes Violator Axle-Back, the car still sounds like a luxury sedan should sound. Powerful but not obnoxious with literally no internal drone.
