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.

    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.
