HSP Diesel 2" Replacement Up-Pipes for 2001-2016 GM Duramax 6.6L LB7/LLY/LBZ/LMM/LML
Upgrade your restrictive factory exhaust restriction with our better flowing 2" up-pipes. Increase horsepower and torque, as well as, reduce your EGTs and increase spool up. Heavy wall 304 stainless steel tubing along with heavy-duty sleeved bellows allow you to push our up-pipes far beyond the capability of a factory up-pipe.
