2004.5-2016 Duramax S300 3" Down Pipe (WCF100122)

3" down pipe for an S300 turbo on a 2004.5-2016 LLY, LBZ, LMM or LML Duramax. It hangs off the HX40 style outlet flange on the turbo and drops to a V-band flange that mates to the exhaust system, so the hot side of an S300 swap bolts together without cutting or welding.

Built for T4 pedestals between 5" and 6" tall, which covers the common single S300 pedestals. The pipe is high-temp coated and ships with the V-band clamp plus heat wrap and clamps to keep underhood temperatures in check.
