Kooks Complete Catted Exhaust System
If you own a 2015-2020 Shelby GT350 and are looking for a complete, catted exhaust system, then this Kooks exhaust kit is the perfect solution. Manufactured from T304 stainless steel tubing, each piece of this kit is engineered to be a direct replacement for your factory GT350 exhaust. This system features stepped headers, cross-over pipes with green catalytic converters, X-Pipe, and Kooks' tried-and-true 3" oval race mufflers.

Kooks Stepped Headers
The stepped headers in this system define the art of "scavenging". These headers start out a 1 3/4" diameter and then widen to 1 7/8" for optimum horsepower and torque. The end of the headers feature a 3" exhaust flange which bolts directly to the included high-flow catalytic converters.

Kooks High-Flow Catalytic Converters
This exhaust system features green catalytic converters incorporated into the same high quality, T304 stainless steel mandrel bent tubing to ensure great exhaust flow for increased power and torque.

Kooks COMP X-Pipe and Mufflers
The Kooks Competition X-pipe features the same T304, mandrel bent stainless tubing and connects to the very popular, 3" oval race mufflers. This muffler design helps achieve a very distinct, aggressive exhaust tone. The mufflers then exit to the quad tips that are 2.5" in diameter and will perfectly fill the factory tips located on the rear valance.
