Product Details

The Gibson Performance Exhaust 315621 is a cat-back single exhaust system built for truck owners who demand real-world low-end power. Engineered to maximize torque and horsepower in the 1,800–3,000 RPM range where it matters most, this system delivers dyno-proven gains of 10–15 horsepower and 15–20 lb-ft of torque. The exhaust exits behind the rear tire and is tuned to remain quieter inside the cab than competing performance exhaust systems.

Gibson Superflow Muffler:

  • Baffled and chambered design with no internal packing
  • Minimal interior drone with an aggressive exterior exhaust note
  • 8 in. round body; 3.00 in. offset inlet; 3.00 in. offset outlet; 24 in. overall length

Tubing & Construction:

  • 3 in. diameter heavy-duty aluminized steel mandrel-bent tubing
  • Mandrel bending maintains consistent diameter through every bend for unrestricted exhaust flow
  • Zinc-plated hangers and clamps included

Exhaust Tip:

  • 4 in. polished T304 stainless steel round slash-cut tip
  • Clamp-on design — no drilling or welding required
  • Tip inlet: 3 in.; Tip outlet: 4 in.; Tip length: 12 in.

Installation & Warranty:

  • Hassle-free bolt-on installation — no welding required

quick great value

Fantastic company! Great selection for every vehicle and fast shipping! I will definitely shop here again.

We ordered a cover for a pickup truck bed and were so pleased that it was shipped so quickly. The price was the lowest that we found on the internet or in any of the stores where we looked. We were notified by e-mail as soon as it shipped. We will definitely shop this site again.

Fast professional service and delivery. Thank You
