Product Details

The Gibson 319618 Cat-Back Single Exhaust System is an aluminized performance exhaust designed to deliver improved acceleration, stronger low-end power, and enhanced towing and passing performance. This bolt-on system exits behind the rear tire and is engineered to remain quieter inside the cab than competing performance exhaust systems.

Dyno-tested results demonstrate peak torque and horsepower gains in the low-end RPM range (1,800–3,000 RPM), with average gains of 10–15 horsepower and 15–20 lb-ft of torque. No welding is required, and the system installs with professional-quality results using existing mounting locations.

Muffler Specifications:

  • Design: Baffled and chambered muffler — no internal packing
  • Sound profile: Aggressive exhaust note with minimal interior drone
  • Shape: 8 in. round body
  • Inlet: 3.00 in. offset
  • Outlet: 3.00 in. offset
  • Length: 24 in.

Exhaust Tip Specifications:

  • Material: Polished T304 stainless steel
  • Style: Round slash-cut tip, clamp-on installation
  • Inlet diameter: 3.00 in.
  • Outlet diameter: 3.5 in.
  • Length: 12 in.

Key Features:

  • Aluminized steel construction for corrosion resistance
  • Bolt-on, no-weld installation — hassle-free fitment
  • Rear exit behind the tire for a clean, factory-style appearance
  • Polished 3.5 in. stainless slash-cut tip included
  • Backed by Gibson's Lifetime Limited Warranty

The Gibson 319618 is an excellent upgrade for drivers seeking a balance of aggressive exhaust sound, measurable performance gains, and a clean installation — all without the need for professional fabrication.

Other than having to refresh the web page to get the "Place Order" to work, all went like a champ.

will be buying more in the future.

Great service, delivered on time.

The door handles purchased work great !

Great tires great price fast shipping thank you!

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

Great pricing and quick shipping. I'll be using them again for sure.

Quick easy painless
