Kooks connection pipes for the S550 / S650 Mustang GT — the crucial mid-section that ties Kooks long tubes into the rest of your exhaust system. Multiple variants are available depending on whether the car is daily-driven street, NA track, or serious boosted build. The right connection pipes preserve power, sound character, and emissions compliance for your specific use case.
Fits 2015-2026 Ford Mustang GT 5.0L (S550 / S650 Coyote). Variants include competition-only (3" race pipes, no cats), standard catted (race cats for NA street), GREEN catted (high-output cats safe for forced induction), and ULTRA GREEN catted (Kooks' highest-flow emissions-friendly cats for serious boosted builds). Requires Kooks long tube headers.
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. Stainless construction handles thermal cycling and corrosion.
Pair with Kooks Coyote long tubes (PN 11512202, 11512402, or 11512602) upstream and a 3" cat-back, axle-back, or Kooks ULTRA X-pipe downstream.
