Extreme Online Store's complete 2008-09 Pontiac G8 (base, GT and GXP) catalog — rear spoilers, exhaust systems and carbon fiber exterior trim, designed and test-fitted on the G8. Engines across the range: the 3.6L V6 in the base car, 6.0L L76 V8 in the GT and 6.2L LS3 in the 2009 GXP.
Base, GT and GXP share the Holden VE-based body, doors and decklid. The GXP adds its own front fascia and rear diffuser, so GXP aero is model-specific while spoilers, hood scoops and trim fit all three. Exhaust systems fit by engine — V6 and V8 systems are different. Use the Category row on the left to go straight to a part type; each listing states the exact trims and model years it fits.
Materials run carbon fiber, dry carbon fiber, ABS plastic and T304 stainless for exhaust. Every carbon fiber part is UV clear-coated for outdoor use; ABS and polypropylene parts ship primed or finished as listed.
Frequently asked
Do you ship free? Yes — free shipping to the 48 contiguous states on every G8 part.
Are these direct fit? Every part here is designed on the actual car and confirmed for fitment. Installation notes and hardware requirements are on each product page.
Carbon fiber or ABS? Carbon fiber is lighter and stiffer with a visible weave under clear coat. ABS is more impact-tolerant and usually ships primed or gloss black — a good choice for splitters that may see driveway contact.
