Kooks 05-09 Ford Mustang GT 4.6L 3V 07-09 Shelby GT-500 Full 3in Cat-back Exhaust

This full 3-inch cat-back exhaust system from Kooks Headers is built using 16-gauge T304 stainless steel tubing, which is known for its strength and resistance to corrosion. It's designed specifically for the 2005-2009 Ford Mustang GT with the 4.6L 3V engine and the 2007-2009 Shelby GT500 with the 5.4L 4V engine. The mandrel-bent tubing ensures consistent pipe diameter throughout, which helps maintain exhaust flow for better performance.

This system features Kooks' polished stainless steel race mufflers and 4-inch slash-cut polished tips, giving your Mustang a more aggressive exhaust note and a distinct look. Because it's a full 3-inch system, it's designed to maximize exhaust gas exit speed and volume, which can lead to improved horsepower and torque. Keep in mind that this cat-back system will not connect to your factory exhaust components; you'll need to pair it with a Kooks X-pipe or H-pipe that has a 3-inch outlet for a complete installation.

Kooks has been crafting performance exhaust systems for over 50 years, and all their products are handcrafted in the USA. This cat-back exhaust comes with the necessary clamps for installation. It carries a limited lifetime warranty to the original purchaser, reflecting the company's confidence in their well-built products.
