Gibson 618810 Cat-Back Single Exhaust System Stainless Steel with Slash-Cut Tip

The Gibson 618810 is a cat-back single exhaust system constructed from stainless steel mandrel-bent tubing, designed to deliver meaningful performance gains with a deep, aggressive exhaust tone. Featuring a swept-side exit behind the rear tire, this system is engineered to minimize interior cab noise while maximizing output where it matters most — in the low-to-mid RPM range.

Dyno-tested performance confirms maximum torque and horsepower gains in the 1,800–3,000 RPM range, with average increases of 10–15 horsepower and 15–20 lb-ft of torque. The system is also engineered to support improved acceleration, hill climbing, towing capacity, and passing power.
