2008-2009 Pontiac G8 GT Headers: 1-7/8" High-Flow Cats Factory Connect, Stainless Works


Calculated at checkout

Stainless Works The Pontiac G8 is a performer, that’s for sure, with a big V8 and rear wheel drive. And it keeps things classy with 4 doors, so there’s plenty of room for the family or business associates. But it is a li’l quiet for our taste, and the log-style manifold is a major choking point in the system.

Uncork the hidden power in this highbrow performance sedan with a pair of high-flowing mandrel-bent stainless steel headers from Stainless Works. They feature beefy ⅜-inch thick mounting flanges, 1 7/8-inch primaries and 3-inch diameter slip fit connectors.

These factory connect headers are designed to attach to your factory Pontiac G8 exhaust system, but with minor trimming. These long-tube headers are much longer than your factory manifold, so the connection to your factory exhaust is further towards the back of the car. All that’s required is to cut off the flange at the front of your factory system, then the headers just slip fit right on.

Notes: Includes high-flowing stainless steel catalytic converters.
