This BBK Catted Down Pipe offers improved rear wheel horsepower and torque as a result of its larger diameter tubing. This aluminized 3" Down Pipe also features a high flowing catalytic converter to help increase the overall performance of your turbocharged Mustang. In addition to the power upgrade, you'll also see a much more aggressive exhaust note - perfect for letting others know that your turbocharged Mustang means business while cruising down the road! 


Though not required, for optimum power gains and smooth operation, we highly recommend a custom tune via handheld programmer, or a pro-tune from your local or online performance shop.
