Description
Unlock Your Pony’s Potential. The Kooks Green Catted Competition Exhaust System is engineered to give your GT350 (or GT350R) a delightfully throaty exhaust note with power to match. The system uses quality, three-inch stainless-steel tubing throughout, paired with high-flow catalytic converters, offering industry-leading power gains.
Complete 3" Competition-Ready Exhaust. Kooks designed the Green Catted Competition Exhaust System to open up the exhaust so your Mustang can breathe. The system starts with crack-resistant, heavy-duty 1-3/4" x 1-7/8" headers, moving through a 304SS X-pipe toward a cat-back with adjustable mufflers designed to rest in the stock spots.
Retains Multi-Mode Exhaust Function. If you’re a fan of the GT350’s multi-mode exhaust feature, which enables you to flip from normal to sport mode, rest assured Kooks has engineered this exhaust system to work with the OEM butterfly valves. This means you can still flip the switch and get a power boost from less restricted exhaust flow on the fly.
Bolt-On Installation. The Kooks Green Competition System requires no welding or cutting for installation. The product bolts on in place of your factory exhaust without modification. While no special tools are required, the job will take even an experienced mechanic most of a day.
Lifetime Warranty. The Green Catted Competition Exhaust System carries a Kooks limited lifetime warranty.
Application. The Kooks Green Catted Competition Exhaust System is engineered for Mustang GT350 and GT350R models manufactured between 2015-2020.
Kooks GREEN Catted products are rated for forced induction applications making up to 750 RHWP and are built to EPA specifications.
