Description
Increase Performance. Eliminate those power robbing factory catalytic converters with a Kooks Off-Road Shorty X-pipe to add even more horsepower and torque to the rear wheels of your 5.0 Coyote Mustang. This Kooks X-pipe is specifically designed to be used with Kooks Long Tube Headers.

Race Car Growl. This free flowing Kooks X-pipe for the 2011-2014 GT Mustangs not only increases power, but it also adds a crisp raspy, race car growl to the sound of your exhaust with its modern "X" crossover pipe design.

Quality Construction. Manufactured from 3" diameter mandrel bent 304 stainless steel tubing, Kooks X-pipes feature a merged "X" crossover for superior exhaust flow.

Application. This Kooks Shorty Off-Road X-Pipe is specifically designed to fit the 2011-2014 5.0L GT Mustangs with Kooks Long-Tube Headers installed. The step down to a 2.75" outlet allows for use of the OEM exhaust. Intended for off-road use, does not include catalytic converters.

Technical Note: This Kooks product is intended for off road use, and is not legal for use in emission restrictive states.

    Kooks headers and shorty off-road x-pipe combo

    Went with this product based on what I've heard about performance gains and it certainly didn't disappoint. A difference you can feel! Car pulls so much better throughout the powerband and sounds amazing too. Get that nice raspy/metallic sound with the x-pipe. Received several compliments on it already. If you're on the fence, take the plunge. You won't regret it!
