Faster, Harder-Working Horses. The Kooks 3 in. Off-Road X-Pipe introduces order into the chaotic output of the two exhaust streams emanating from each cylinder bank. The end result is an increase in torque, or amount of work produced by the engine, and horsepower—how quickly the engine can deliver that work. You and your Pony ultimately benefit from higher performance.

Quieter, More Pleasing Noise Output. Another consequence of a more efficient exhaust stream is a decrease in noise production to the tune of about 2 decibels. What noise does come out is at a higher, more appealing tone.

No Cat Zone. Kooks designed its 3 in. Off-Road X-Pipe to work without a power-sucking catalytic converter. The price you pay for enhanced performance is being unable to drive your 2015-2019 Mustang GT350 on the street. Are you bothered? You came here to race.

Durable Construction. The Kooks 3 in. Off-Road X-Pipe is manufactured from versatile, durable, corrosion-resistant 304 stainless steel. This grade is good enough for aircrafts, so it's good enough for your Mustang GT350.

Application. The Kooks 3 in. Off-Road X-Pipe has been designed specifically for use with 2015 to 2019 Mustang G350s with Long Tube Headers.
