BBK's High Flow X-pipe is designed to turn your factory H-pipe into a more efficient X-pipe while keeping the stock catalytic converters in place for emissions legality while increasing horsepower and torque.

Made from 2 3/4" mandrel bent aluminized tubing, this X-pipe will add power while noticeably improving the exhaust note of your Mustang.

This part is also compatible with BBK's Mustang Shorty Headers and BBK's Off-Road Pipes.

When combined with BBK's off road pipe, you will see gains of up to 18 horsepower at the wheels over stock.
