2007-2014 GMC Sierra 3500HD Exhausts

Aftermarket exhaust systems built for the 2007-2014 GMC Sierra 3500HD, covering both 6.0L Vortec gas and 6.6L Duramax LMM/LML diesel trucks. Cat-back, DPF-back, and turbo-back configurations from MBRP, Flowmaster, MagnaFlow, and aFe Power, with 4-inch and 5-inch stainless options for single- and dual-rear-wheel beds.

Will a cat-back exhaust throw a check engine light or cause emissions issues? No. Cat-back systems replace piping downstream of the catalytic converter, leaving all factory emissions equipment intact, so no CEL and 50-state legal on gas trucks.

Verified fitment for your Sierra 3500HD, no guesswork.
