A cat-back or axle-back exhaust adds sound and frees up flow on your Sierra 1500 without touching the emissions equipment up front.
- Engine comes first: 5.3L, 6.2L, 2.7L and Duramax trucks use different systems.
- Cab and bed set the pipe length, so match your configuration.
- Sound level: each listing notes whether it's mild, aggressive or somewhere between.
Select your truck in the vehicle bar above to see systems that fit.

GMC Sierra 1500 fitment tips
- Sierra and Silverado beds are the same sizes (5 ft 10 in, 6 ft 7 in and 8 ft), but front bumpers, grille guards and lighting are GMC-specific.
- The 2022 refresh split many front-end fitments into 2019–2021 and 2022+.
- AT4 and AT4X models have factory lift and unique bumpers, so check fitment notes for leveling and lift kits.
- The MultiPro tailgate can affect tailgate seals and some bed covers.
- Not sure about your trim, cab or bed length? Use the vehicle selector at the top of the page, or contact us with your VIN and we'll confirm fitment before you order.
