Wehrli's full 3 in. steel down pipe takes the place of the restrictive, crushed factory turbo down pipe / front exhaust pipe on 2004.5-2010 6.6L Duramax trucks. It has a black high-temperature ceramic coating and comes with heat wrap.
It works with the factory turbo or a factory-style drop-in turbo, and no tuning is needed.
LLY, LBZ and LMM owners on a stock or drop-in turbo who want a freer-flowing down pipe.
