    Improves Rotational Force and Power. You will massively boost the power and performance of your Mustang when you install Stainless Works Long Tube Headers w/ Off-Road X-Pipe.

    Increased exhaust Sound. Stainless Works integrated 3” diameter high-flow X-Pipe not only improves the performance of your Mustang but also adds a more aggressive race car exhaust growl with its unique ‘X’ crossover design.

    Superior Construction. Stainless Works Headers are designed and manufactured in United States, crafted from a TIG welded 304 stainless steel for an excellent leak proof performance. The exterior is also finished with a bright polish for an impressive durable look.

    No tuning is required. Stainless Works headers are engineered to increase the performance of your Mustang without any need of reprogramming your vehicle’s Computer system. They automatically blend with the vehicle’s factory tune due to their exceptional computer-aided designs. However, to realize the full performance potential of these headers, a custom tune to reprogram the Mustang’s computer(ECU) is always recommended.

    Not CARB Certified. Stainless Works Headers are not CARB certified. It’s intended for off-road use only.

    Handy Installation. Installing Stainless Works Long Tube Headers w/ Off-Road X-Pipe is designed as bolt-on and comes with all the necessary mounting hardware. However, professional skill is required to install and the process takes approximately 14 hours.

      Awesome headers for GT500

      These headers sound great and give the car an even more aggressive feel. the only issue i have run into is that the steering column just barely rubs the header on the driver side so i was forced to upgrade the motor mounts to fix this issue.
