Kooks 11-14 Ford Mustang GT 5.0L 4V 3in x 2 3/4in OEM Exhaust GREEN Cat X Pipe Kooks HDR Req

Starting with 16-gauge 304 stainless steel construction, this Kooks X-pipe is built to handle the demands of your 2011-2014 Mustang GT 5.0L. This isn't just about making noise; it's about optimizing how your engine breathes. The X-pipe design helps scavenge exhaust gases more efficiently than a standard H-pipe, which can lead to an improved throttle response and a more aggressive exhaust note.

This X-pipe features Kooks' GREEN high-flow catalytic converters, rated at 400 cells per inch, designed to reduce restriction while still meeting emissions requirements for most areas. It's specifically engineered to connect to Kooks Long Tube Headers using a ball and socket style connection, ensuring a solid seal. The 2-3/4 inch outlet is designed to mate with your factory exhaust system, utilizing your original clamps for a straightforward installation. Keep in mind that this system is not CARB approved and cannot be shipped to California.

For those running forced induction, Kooks GREEN cats are suitable for use with superchargers or turbochargers. This X-pipe is intended to be used as part of a Kooks Headers system for optimal performance and fitment. If you're looking to unlock more power and a distinct sound from your Mustang GT, this X-pipe is a well-built option.
