Gibson CFT Superflow Offset/Center Oval Muffler - 4x9x13in/2in Inlet/2.25in Outlet - Stainless

This Gibson CFT Superflow muffler is a well-built unit featuring a 4-inch by 9-inch by 13-inch oval body with a 2-inch inlet and a 2.25-inch outlet. It's constructed from stainless steel and is fully welded for solid internal construction. This muffler uses resonance chambers and directional louvered tuning ports to help draw exhaust gases through, aiming for increased exhaust flow and a deeper tone.

Unlike packed mufflers that can degrade over time, this non-packed design aims to maintain its sound characteristics. The chambered and louvered core is designed to create better volume efficiency and help expel exhaust gases at a higher velocity, which Gibson states can result in more power. It's also reversible, meaning you can install it in either direction.
