Product Details

The Gibson 615534 is a cat-back single side exhaust system built with 3-inch 409 stainless steel mandrel-bent tubing for unrestricted exhaust flow and long-lasting corrosion resistance. Engineered and dyno-tested to maximize power output in the low-to-mid RPM range, this system delivers meaningful gains in both horsepower and torque for trucks and SUVs.

At the heart of the system is Gibson's Superflow baffled and chambered muffler — a design that eliminates internal packing to deliver an aggressive exterior tone while keeping interior cabin noise to a minimum. The system exits cleanly behind the rear tire for a factory-clean appearance with genuine performance results.

  • Body: 8 in. round
  • Inlet: 2.50 in. dual inlet
  • Outlet: 3 in. offset outlet
  • Length: 24 in.
  • Sound profile: Minimal interior drone, aggressive exterior tone

  • Style: Round slash-cut, clamp-on
  • Material: Polished T304 stainless steel
  • Inlet: 3 in.

  • Backed by a Lifetime Limited Warranty

The Gibson 615534 is a direct-fit, no-weld performance exhaust upgrade designed to improve acceleration, towing, hill climbing, and passing power. Dyno testing shows peak torque and horsepower gains in the 1,800–3,000 RPM range — exactly where everyday driving and towing demand them most.

They had an item that was somewhat hard to find at a reasonable price. Glad I found them.

For the over-the-winter garage storage of my 911, the Rail Ramps Flatstopper product has eliminated the need to move the car over the winter in order to avoid the tires developing flat spots.

The best prices and fast shipping!

Absolutely the best bargain you'll find! Don't pay retail mark up at the parts store, buy at Autoplicity and know you're saving money.<br>.

great service, even better price! Would recommend Autoplicity to anyone.

Easy website to shop on. Good phone support. Package will be arriving in a timely manner. All in all seems like a good company.
