Kooks 3" x 2-1/2" (OEM-style outlet) stainless competition-only X-pipe — the bolt-in race mid-section that ties Kooks long tubes into the OEM mufflers on the G8. X-pipe geometry balances exhaust pulses between cylinder banks for smoother top-end power. Competition only — no cats; off-road / track use only.
Fits 2008-2009 Pontiac G8 GT / GXP (LS2 / LS3 6.0L / 6.2L). Requires Kooks long tube headers (PN 24202400).
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every X-pipe is welded by experienced fabricators in the same shop where the company's racing roots were established. Stainless construction handles thermal cycling and corrosion.
Pair with Kooks G8 long tubes (PN 24202400) upstream and the OEM cat-back downstream.
