Gibson 2019-2022 GMC Sierra 1500 Denali 5.3L 3in/2.5in Cat-Back Dual Split Exhaust - Stainless

Transform your truck with the Gibson 65688 stainless steel cat-back dual split exhaust system designed for 2019-2023 Chevrolet Silverado 1500 and GMC Sierra 1500 models equipped with the 5.3L engine. This performance exhaust reduces backpressure to deliver average gains of 18-20 horsepower and increased torque while producing an aggressive throaty sound that intensifies under towing. The bolt-on design ensures straightforward installation using factory hanger locations and exhaust tips that exit straight out the back.

Key Features

  • Stainless Steel Construction: Tubing and muffler built from heavy-duty stainless steel for corrosion resistance and long-term durability in harsh conditions.
  • 3in to 2.5in Mandrel-Bent Tubing: Smooth bends maintain exhaust flow, minimizing restrictions for optimal power and throttle response across the RPM range.
  • Dual Split Rear Exit Design: Splits into dual outlets using factory tips for a clean stock appearance with enhanced sound and visual appeal.
  • Power Gains: Dyno-tested to increase horsepower by 18-20 and torque for better acceleration, towing capability, and overall drivability.
  • Superflow Mufflers: Patented straight-through design quiets drone while amplifying deep throaty tone, especially noticeable when loaded or hauling.

Product Notes

  • Exhaust sound volume increases during towing or heavy loads for improved driver awareness.
  • Retains factory exhaust tips and tailpipe positioning for seamless integration.
  • Backed by Gibson Lifetime Limited Warranty against defects in materials and workmanship.

Installation Notes

  • Professional installation recommended.
