This dual split cat-back exhaust from Gibson transforms your 2007-2013 Chevrolet Avalanche LS 5.3L with an aggressive throaty sound and head-turning look. It fits select 2007-2014 Chevrolet Suburban 1500 and GMC Yukon XL 1500 models too, reducing backpressure for average gains of 15-20 horsepower and more torque.

  • Accessory Compatibility: Designed to clear most factory bumpers, roll pans, and trailer hitches without modifications
  • Bolt-On Installation: Direct-fit muffler and hangers use factory mounting points with no welding, cutting, or fabrication needed
