PRODUCT DESCRIPTION

Kooks Header & Off Road X-Pipe Kit
Bolt on improved power and sound to your 2011-2014 Mustang GT with this long tube header and X-pipe kit from Kooks! When it comes to quality, Kooks stands out from the rest in the exhaust industry, and this header kit is no exception. Constructed with high quality, 304 Stainless Steel, this exhaust kit is built to last. Massive 1-7/8" primary tubes flow into a 3" collector to provide the best flow possible. These collectors bolt to the included 3", off road X-pipe that replaces your restrictive catalytic converters to further improve flow. Kooks utilizes TIG welding throughout to ensure long lasting, leak free performance! The included off road X-pipe has a 2-3/4" outlet to bolt to your factory cat back, or any aftermarket cat back with a 2-3/4" connection.

Emissions Note
