    Attention-Grabbing Exhaust Tone. Nothing announces your arrival better than a loud exhaust growl. Installing MAC’s 2.5 in. Aluminized Steel Off-Road X-Pipe on your 99-04 Mustang GT or Cobra can help you achieve just that. This x-pipe is designed to upgrade your Mustang’s hitherto gentle purr into an attention-grabbing growl which will certainly turn heads. With it, everyone on the trail will know that you are in charge.

    Performance Gains. Installing the X-pipe on your Mustang gives the vehicle an unprecedented performance boost in terms of improvements in torque, horsepower, and throttle response. Its free-flowing mandrel-bent design allows more exhaust flow while minimizing back flow thus boosting your ride’s performance. Nonetheless, the X-pipe is not street legal and therefore you can only use it for off-road applications such as trail racing.

    Tough Construction. To enable this X-pipe withstand the aggressive driving applications that are in store for it, MAC assembled it from high-strength aluminized steel. This enhances its resistance to rust, corrosion, and high exhaust temperatures. An aluminum-silicon coating is similarly used to enhance corrosion resistance thus guaranteeing years of reliable service.

    Professional Installation. You need considerable technical skills for you to perfectly mount this X-pipe to your Mustang’s stock exhaust system. Mounting clamps are required and the process doesn’t necessitate the need for significant modifications to stock parts.

    Warranty Information. MAC covers its X-pipes with a comprehensive limited lifetime warranty against workmanship and material defects.

    Application. MAC 2.5 in. Aluminized Steel Off-Road X-Pipe is designed to fit all 1999 to 2004 Mustang GT & Cobra models.
