2008-2009 Pontiac G8 GT Pypes Long Tube Exhaust Headers

* Tri Y design
* Primary Tube Diameter (in) 1 3/4 in.
* Collector Diameter 2.50 in.
* T-304 polished stainless
* Incredible price 

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!

Requires (1) oxygen sensor extension that is 12" long for the driver side Bank 1 Sensor 1
Summit Racing carries a 12" Casper Electromics o2 sensor extension (PART# 109006).

Best Headers for the Price
You just cannot get a better header for your G8 GT or GXP for the price. Actual stainless steel and fit perfect. Bolt directly to the stock catback. And GTOG8TA has a great price and fast shipping. These will make your car SLIGHTLY louder. Most people won't be able to tell you have headers they are so quiet.

I gave these only 4 stars as the donut gaskets for connecting the catback are terrible and will leak; just re-use the donut gaskets on the stock cats. Also, the bolts provided are too small and weak. I recommend getting 4 stainless M10x1.5 50mm length bolts and nuts from your local Lowes. You will also need a 12 inch O2 extension for the driver's side which is not included.

Overall, this is still a great product at a bargain.
