Description

The Kooks 12-Inch Polished Stainless Steel Center/Center Oval Clamp-In Muffler is designed for efficient exhaust flow management. It clamps securely onto 3-inch tubing to reduce exhaust noise while maintaining performance. Crafted from polished 304 stainless steel, this muffler features a durable oval body.

Installation is straightforward and requires no welding, as it includes two JI-TAS300 clamps. Some minor adaptation may be necessary for a proper slip-fit. This muffler is sold individually and fits universal applications. It comes with a comprehensive warranty.
