Product Details

The Gibson 7400 Cat-Back Dual Split Exhaust System delivers the aggressive sound, bold styling, and real performance gains that truck and SUV enthusiasts demand. Constructed from mandrel-bent, heavy-duty aluminized steel tubing, this system is built to handle tough conditions while maximizing exhaust flow and long-term durability.

Performance You Can Feel:

  • Reduces exhaust backpressure for improved engine efficiency
  • Dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque in the 1,800–3,000 RPM range
  • Optimized for low-end power where trucks and SUVs need it most

Gibson Superflow Muffler Specs:

  • Baffled and chambered muffler design — no internal packing
  • Deep, aggressive exhaust note with minimal interior cabin drone
  • 8 in. round muffler body; 2.50 in. dual inlet; 3 in. offset outlet; 24 in. body length

Exhaust Tip Specs:

  • 3.50 in. polished T304 stainless steel round slash-cut tips
  • Clamp-on design; tip inlet 2.50 in., outlet 3.50 in., length 12 in.
  • Exits straight out the back — compatible with most factory bumpers, roll pans, and trailer hitches

Construction & Installation:

  • 2.50 in. aluminized mandrel-bent tubing throughout
  • Hassle-free bolt-on installation — no cutting or welding required
  • Includes all necessary hardware and factory-style hangers and clamps
  • Note: Exhaust sound level increases under towing conditions

Proudly made in the USA and backed by Gibson's Lifetime Limited Warranty, the 7400 is a proven upgrade for drivers who want more power, a commanding exhaust tone, and a clean dual-tip appearance straight out of the box.
