Kooks 05-10 Ford Mustang GT Shelby GT Bullitt 1-5/8 x 2-1/2 (3V) Header & Green Catted X-Pipe Kit

If you're looking to get the most out of your 2005-2010 Ford Mustang GT's 4.6L 3V engine, this Kooks Headers and Green Catted X-Pipe kit is a serious upgrade for your exhaust system. This kit is designed to help your engine breathe easier, which can lead to improved throttle response and a more aggressive exhaust note.

Kooks builds these headers and X-pipe from 16-gauge T304 stainless steel, known for its strength and resistance to corrosion. The headers feature 1-5/8 inch mandrel-bent primary tubes that smoothly transition into 2-1/2 inch collectors, all attached to a beefy 3/8 inch thick laser-cut flange that mates directly to the stock bolt pattern. The included X-pipe is also made from T304 stainless steel and features Kooks' GREEN catalytic converters. These are EPA-verified 400-cell high-flow converters designed to be suitable for use with forced induction setups, offering a balance between emissions compliance and exhaust flow. The 2-1/2 inch outlet on the X-pipe is designed to connect to your factory exhaust system.

This kit comes with all the necessary hardware for installation, making it a straightforward bolt-on process for most mechanics. Kooks has been in the performance exhaust business for over 50 years, and every product they make is tested on the dyno and at the track to ensure it performs as expected. This kit is manufactured 100 percent in the USA.
