Extreme Online Store's complete 2019-Up GMC Sierra 1500 (T1 platform) catalog — exhaust systems, designed and test-fitted on the Sierra. Engines across the range: the 2.7L turbo four, 5.3L and 6.2L V8s and the 3.0L Duramax diesel.
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. Use the Category row on the left to go straight to a part type; each listing states the exact trims and model years it fits.
Shop by category: Exhaust Systems.
Exhaust systems here are T304 stainless steel, mandrel-bent and TIG-welded, with chrome, black and carbon fiber tip options. Each listing states whether the system is resonated or non-resonated.

Are these direct fit? Every part here is designed on the actual truck and confirmed for fitment. Installation notes and hardware requirements are on each product page.
