    Enhanced Exhaust Note. The principle rule with exhaust systems is; with an accelerated flow, the more the sound. In simple terms, the Kooks 1-3/4 in. Stepped Stainless Steel Long Tube Headers give your supercharged Mustang GT350 a more aggressive roar when the baffles open up. Once you have your foot on the pedal, you accelerate with more throttle.

    Enhanced Horsepower and Torque. Kooks Long Tube Headers feature a high-performance venturi exhaust collection tube that increases the scavenging rate and reduces exhaust turbulence for a perfect flow. This bolsters power and throttle, thereby increasing your Ford GT350’s acceleration.

    Superior Construction. Kooks Long Tube Headers are engineered using premium 1-3/4" Mandrel-Bent 304-Grade Stainless Steel tubes that provide the strength and endurance needed for high exhaust temperatures. In fact, they are robust enough to withstand up to 1500 degrees. Atop that, its chrome finish protects it from corrosion.

    Easy, Bolt-On Mounting. Kooks designs its 304 Stepped Stainless Steel Long Tube Headers to be a direct replacement for the stock manifolds. They come with predrilled bolt holes and are easily installable using simple tools. For ultimate performance, Long Tube Headers must work with Y-Pipe or H-Pipe.

    Warranty. Kooks guarantees the original product consumer with a Limited Lifetime Warranty.

    Application. Kooks 1-3/4-inch Stepped Stainless Steel Long Tube Headers are crafted to fit all Mustang GT350 models, manufactured between 2015 and 2018.
