Premium stainless steel 4" down pipe engineered for 1999-2013 full-size GM trucks running LS-based engines with turbocharging. This two-piece assembly features TIG welding with back purging for maximum durability and reliability under boost.
Designed to pair with our T6 stainless turbo manifold and 1.32AR T6 turbo housing. Includes turbo flange, clamp for turbo connection, 2-piece junction clamp, and one welded bung. Note that fitment may require modifications if using alternative manifolds or different AR exhaust housings. Pictures are for reference only. Allow 2-3 weeks for build time.
Important: This down pipe has no waste gate connection. Intended for off-road and motorsport applications only—not for highway or street use.
