Product Details

The Gibson 6515 Cat-Back Dual Split Exhaust System is engineered for truck and SUV enthusiasts who demand an aggressive exhaust note, a bold dual-tip appearance, and real performance gains. Built from heavy-duty aluminized steel mandrel-bent tubing, this cat-back system reduces exhaust backpressure to unlock more torque and horsepower across the RPM range.

Performance:

  • Decreases backpressure to produce more torque and increased horsepower
  • Typical horsepower gains average 15–20 hp
  • 2.5-in. aluminized mandrel-bent tubing for maximum flow

Gibson Superflow Muffler:

  • Baffled and chambered muffler design — no internal packing
  • Delivers an aggressive, throaty exhaust tone
  • Minimal interior drone for a comfortable daily driving experience
  • Muffler dimensions: 7 in. round; 3 in. center inlet; 2.50 in. dual outlet; 24 in. length

Exhaust Tips:

  • 3.5 in. polished T304 stainless steel round slash-cut tips
  • Clamp-on mounting — no permanent modification required
  • Tip specs: 2.50 in. inlet; 3.50 in. outlet; 12 in. length
  • Dual tips exit straight out the rear for a clean, aggressive look

Installation & Compatibility:

  • Hassle-free bolt-on installation — no welding required
  • Includes all necessary hardware and factory-style hangers
  • Compatible with most factory bumpers, roll pans, and trailer hitches
  • Note: Exhaust sound may be louder under towing conditions

Made in the USA and backed by Gibson's Lifetime Limited Warranty, the 6515 is a proven upgrade for drivers who want more power and a commanding exhaust presence.
