This stainless steel exhaust kit by Kooks is engineered to fit 2005–2006 Pontiac GTO models with a 6.0L LS2 V8, offering improved exhaust flow and durable construction.
It includes a pair of long tube headers and high-flow catted connection pipes, designed to maintain compatibility with stock and aftermarket exhaust systems.
The headers feature 1-7/8-inch primary tubes constructed from mandrel-bent 304 stainless steel, offering enhanced scavenging and consistent flow across all cylinders. The accompanying 3-inch catted connection pipes utilize Kooks’ GREEN catalytic converters, designed to meet stringent emissions requirements while still supporting performance applications. TIG-welded for strength and corrosion resistance, the entire system is built to deliver a factory-like fit and trouble-free installation with included O2 sensor bungs and flanges.
This kit is ideal for GTO owners seeking a bolt-on solution that preserves street legality while offering measurable performance enhancements through freer exhaust movement.
