The MagnaFlow direct-fit catalytic converter for 2008–2009 Pontiac G8 3.6L provides an EPA-compliant replacement that helps prevent check-engine codes. Built to mirror OE shape and flow, it uses mandrel-bent tubing, corrosion-resistant stainless steel and a spun-body design with a single laser fusion weld to limit leaks. Essential gaskets are included for a secure seal, and the compact design supports direct installation with common tools—no cutting or welding required.
