Kooks 3" x 2-3/4" stainless X-pipe — the bolt-in race mid-section between Kooks GT500 long tubes and the OEM cat-back. X-pipe geometry balances exhaust pulses between cylinder banks for smoother top-end power. Competition only — no cats; off-road / track use only. Ball-and-socket header connection accommodates thermal expansion.
Fits 2011-2014 Ford Shelby GT500 (5.4L / 5.8L 4V). Requires Kooks long tube headers. The 2-3/4" outlet connects to OEM exhaust at the factory connection point (OEM clamps not included). Right choice for GT500 owners keeping the OEM cat-back.
Kooks Headers & Exhaust has been hand-building stainless headers and exhaust systems in Statesville, North Carolina since 1962. Every mid-section is welded by experienced fabricators in the same shop where the company's racing roots were established. 16 gauge 304 stainless construction handles supercharged heat and corrosion.
X-pipe clamps are included for the header connection. Pair with Kooks GT500 long tubes (PN 11422200 or 11422400) upstream and the OEM cat-back downstream.
