Main Features

• These kits use a 4" T-Pipe that sits sits in the bed, and only one hole needs to be cut in the bed of the truck.
• A 4" underbed 90 degree bend connects to your stock (or aftermarket) exhaust between the cab & truck bed.
• A small section of stainless flex pipe goes between the 90 degree elbow and the existing exhaust on your truck, to allow the bed and cab to flex without causing damage to the exhaust.
• Choose your reducers for trucks that have 3" & 3.5" exhausts, so everything you need is included!
• These stack kits sound great on Ford Powerstrokes, Dodge Cummins & Chevrolet/GM Duramax Diesel Pickups!
