2007-2014 GMC Sierra 3500HD AxleBack Exhausts

Axle-back exhaust systems guaranteed to fit your 2007-2014 GMC Sierra 3500HD, single or dual rear wheel. Stocked options from MBRP, Flowmaster, MagnaFlow, and Borla cover the 6.0L gas V8 and 6.6L Duramax LMM and LML diesel configurations.

Will an axle-back void my powertrain warranty? No. Axle-back systems replace only the muffler and tailpipe behind the rear axle, so factory cats and sensors stay untouched and emissions-legal in all 50 states.

Every listing here is verified against your Sierra 3500HD, no guesswork.
