Exhaust Systems for the 2019-Up GMC Sierra 1500 (T1 platform): axle-back mufflers, full cat-back systems, downpipes and front pipes, mid-pipes, valve simulators and muffler deletes in T304 stainless, with chrome, black and carbon tip options. Exhaust is the one upgrade you hear every single drive. Everything on this page is confirmed for Sierra fitment.
All trims share the cab, bed and doors; AT4 and Denali add their own grilles and bumpers. The 2022 refresh redesigned the interior and front fascia, so dash and grille pieces are 2019-21 or 2022-Up. The Sierra shares its chassis and drivetrain with the Silverado 1500, so exhaust systems cross over by engine and bed length. This page covers Pro / SLE, Elevation / SLT, AT4 / AT4X and Denali / Denali Ultimate; each listing states the exact trims and model years it fits.
Materials run T304 stainless steel. Systems are mandrel-bent and TIG-welded; each listing states resonated or non-resonated and the tip finish.
Frequently asked
Will I get drone at highway speed? Resonated systems here are tuned to stay quiet at cruise and open up under throttle. Non-resonated and muffler-delete options are louder throughout and say so.
Do I need a tune? Axle-back and cat-back systems are bolt-on with no tune required. Downpipes and header changes are the only ones that may need one — each listing states it.
