Kooks 1-3/4" x 1-7/8" x 3" SS Stepped Headers (2015-2020 Shelby GT350)

PRODUCT DESCRIPTION

GT350 Kooks Long Tube Header Kit
The Shelby GT350 can turn some serious RPM in factory trim. With this amount of RPM, you want your engine to be able to expel its exhaust as easily as possible. Kooks' stepped long tube headers are designed to allow your VooDoo engine to do just that! The primary tubes are 1-3/4" that step up to 1-7/8" diameter! The reason for this stepped design is to allow for an easier installation, increased high end power, and more low end torque. The flow of an 1-7/8" diameter for high end power, and the low end torque of an 1-3/4" header gives you the best of both worlds! An off road X-pipe is included to provide the maximum flow possible!

Kooks Quality
When it comes to quality, Kooks stands out from the rest in the exhaust industry, and this header kit is no exception. Kooks constructs this long tube header kit with high quality, 304 Stainless Steel, that's built to last! All tubing is mandrel bent for uninterrupted flow, and finished off with TIG welding for leak free performance!

Emissions Note
Due to the off road design, this kit will not pass emissions testing.

Installation/Tune Note
-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.
