08-09 Pontiac G8 Long Tube Headers 304SS HDR140S

Pricing: $472.77


How It Sounds


* Primary Tube Diameter (in) 1 3/4 in.
* Collector Diameter 2.500 in.
* T-304 stainless steel

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 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 AxleBack, the car still sounds like a luxury sedan should sound. Powerful but not obnoxious with literally no internal drone!

Sounds really good on car. It just causes whole catback to shift to side causing it to be pinned against exhaust tunnel side making vehicle vibrate. Going put vehicle on lift and see if any adjustments can be made.
