Product Details

The Gibson Exhaust 65689 Cat-Back Dual Split Rear Exhaust System is engineered specifically for Chevy Silverado trucks, delivering an aggressive throaty sound and bold styling that enthusiasts demand. This performance exhaust system features a baffled and chambered muffler design that reduces backpressure to unlock additional horsepower and torque, with typical gains averaging 18-20 horsepower over stock exhaust systems.

Key Features:

  • Complete cat-back dual split rear exit system in stainless steel construction
  • Baffled and chambered muffler design with no internal packing for long-lasting performance
  • Round muffler body (8" diameter, 24" length) with 3" offset inlet and dual 2.5" outlets
  • Dual 4" polished T304 stainless steel rolled slash-cut tips for premium appearance
  • Tips feature 2.5" inlet, 4" outlet, 12" length with clamp-on installation
  • Straight-out-the-back exit design works with most bumpers, roll pans, and trailer hitches
  • Minimal interior drone for comfortable daily driving
  • Bolt-on installation with no welding required
  • Includes stainless steel band clamps for secure connections

This exhaust system produces an aggressive exhaust note that becomes more pronounced under load and towing conditions. Gibson backs this Cat-Back Dual Split Exhaust System with a Lifetime Limited Warranty for long-term peace of mind.
