We put these on our Pro-Charged G8 GT and with only 6lb of boost hit over 500hp 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 midpipe. 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 AxleBack, the car still sounds like a luxury sedan should sound. Powerful but not obnoxious with literally no internal drone!
