Kooks Complete Catted Exhaust System
If you own a 2015-2018 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 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 high-flow 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.
-Installation of long tube headers will require custom tune to prevent damage to your vehicle. If you already have a custom tune on your Mustang, please consult with your tuner prior to installation and operating your Mustang.
