2007-2014 GMC Sierra 2500HD CatBack Exhausts

Cat-back exhaust systems built for the 2007-2014 GMC Sierra 2500HD with the 6.0L Vortec and 6.6L Duramax. Stocked options from MBRP, Flowmaster, MagnaFlow, and Borla in single-side, dual-side, and behind-tire exits with 4-inch and 5-inch tips.

Will a cat-back trigger a check engine light or fail emissions? No -- cat-back systems replace only the piping after the catalytic converter, so factory cats and O2 sensors stay untouched and the truck remains 50-state legal.

Verified fitment for your Sierra 2500HD, no guesswork.
