Product Details

The Gibson 65655 Dual Extreme Cat-Back Exhaust System is engineered for performance enthusiasts who demand aggressive sound, bold styling, and real power gains from their truck. This complete bolt-on system exits behind the rear tires at an aggressive angle, delivering a commanding exhaust note and a head-turning street presence without the need for cutting or welding.

Key Features:

  • Dual exit cat-back exhaust system — mounts entirely behind the rear tires
  • Dyno-tuned and tested for measurable street performance gains averaging 15–20 horsepower
  • Gibson performance muffler engineered for a deep, aggressive exhaust tone
  • Finished with polished stainless steel exhaust tips for premium street appearance
  • True bolt-on installation — no cutting, no welding, no fabrication required
  • Backed by Gibson's Lifetime Limited Warranty

The 65655 is part of Gibson's Extreme series, designed specifically for truck owners looking to maximize both performance and presence. The system utilizes mandrel-bent tubing to reduce exhaust backpressure, helping unlock power that is otherwise lost through restrictive factory exhaust components. The polished stainless steel tips provide a lasting, corrosion-resistant finish that complements any truck build.
