These 2-inch up-pipes from HSP Diesel replace the restrictive factory exhaust components with heavy wall 304 stainless steel tubing and heavy-duty sleeved bellows. They boost horsepower and torque while lowering exhaust gas temperatures and improving turbo spool-up.

Designed for 2001-2004 Chevy and GMC trucks with the LB7 engine (VIN Code 1), the kit includes both passenger and driver side up-pipes along with turbo and manifold gaskets for a complete installation.
