The Gibson Exhaust 615506 Cat-Back Single Exhaust System delivers exceptional performance gains for trucks and SUVs requiring improved acceleration, towing capacity, and passing power. Engineered with premium T304 stainless steel construction, this complete cat-back system features a side-exit design that routes exhaust behind the rear tire for optimal ground clearance and a distinctive appearance.

  • Maximum torque and horsepower optimization in the low-end RPM range (1800-3000 RPM)
  • Improved throttle response for better hill climbing and towing capability
  • Reduced exhaust backpressure for enhanced engine efficiency

Muffler Specifications:

  • Baffled and chambered muffler design with no internal packing for long-lasting durability
  • 8-inch round body with 24-inch overall length
  • Dual 2.5-inch inlets and 3-inch offset outlet
  • Aggressive exhaust note with minimal interior cabin drone

Exhaust Tip Details:

Above average website speed. Organization is very good. Prices are excellent.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

Wow talk about FAST shipping...I placed the order...and the door bell rang for delivery!!! The electronic points and coil when in the FJ 4o in just a few minutes and work perfectly...THANKS so much! Larry in Montana

So far i am happy with your service.

I liked the ability to pay with PayPal. It was quick and easy. It was unbelievable how quickly the order was received-And with free shipping! Great experience!
