Hopped- Up Performance and Horsepower. These LTHs by Kooks are crafted with an integrated venturi style collection tube that heightens exhaust scavenging while reducing gas turbulence for a smooth flow. That boosts the horsepower and torque coefficients.

Improved Exhaust Note. With an increased exhaust flow, the more the sound. Simply put, unlike the stock manifolds, the Kooks Stainless Steel Long Tube Headers. With a supercharger as a Mustang motor, these headers get louder when the baffles open. The effect? You get a consistent crisp roar whenever you step on the go pedal.

Quality Construction. Proudly in U.S, the production of this Kooks header meets the required quality threshold. It utilizes high-quality 1-5/8" mandrel-bent 304-grade stainless steel tubing for an accelerated gas flow. The header is TIG welded to render it leak-free. It is polished surface makes the steel highly resistant to rust.

Quick, Bolt-On Installation. Methodically designed, the Kooks Stainless Steel LTHs are direct replacement upgrade for OE manifolds. They are easily installed through bolting but perform optimally with H-Pipes and Y-Pipes.

Warranty. Kooks backs the quality of their Kooks 1-5/8" SS LTHs by a Limited Lifetime Warranty. Nonetheless, valid to the original product consumer.

Application. The Kooks 1-5/8 in. x 3-inch Stainless Steel Long Tube Headers fits 2011-2014 Ford Mustang GT models.
