      More Power, Faster. The improved efficiency imparted by the Kooks 3 in. Tuner Catted X-Pipe to the dual exhaust streams impacts performance in two ways. Higher torque enables the engine to do a larger quantity of work, while the boost in horsepower lets the engine perform that work at a faster rate. And you? You get to drive a faster, more powerful 2015 to 2020 Mustang GT350 on the racetrack.

      More Power, Less Noise. Apart from increased horsepower and torque, another offshoot of the Kooks Tuner Catted X-Pipe's ability to coax more spent exhaust out of the engine cylinders is a higher tone at a lower volume. The resulting voice of your Mustang is exactly what you would expect—or rather, demand—of such an exotic ride.

      Hello, Kitty. Kooks' high-flow tuner catalytic converter meets stringent EPA Federal Emission Standards. The Tuner Catted X-Pipe is still not street legal in California and other states. Meh. Their loss.

      Premium 304 Steel. Kooks proudly makes its Off-Road X-Pipe from premium-grade 304 stainless steel. This is the stuff of which aircrafts, and dreams, are made. This particular grade of steel is chosen for its durability and resistance to corrosion.

      Application. The Kooks 3 in. Tuner Catted X-Pipe has been custom designed to fit all models of 2015 to 2020 Mustang G350 with long tube headers.
