2.5 Skyactiv performance header for the Mazda 6 and Mazda 3


The one-of-a-kind Race Header for the 2014-2018 Mazda 3 & Mazda 6 2.5L takes your Mazda to the next level. Utilizing the same 4-2-1 design as OE, but with performance as the key focus. Long tube primaries and secondary runners are used to boost mid-range torque where the vehicle is most commonly driven vs just peak engine RPM. This boost in mid-range power and torque makes your Mazda even more fun and easy to drive

For Mazda 3 applications, pair the Race Header with the CorkSport 80mm Cat-Back Exhaust system for some truly exhilarating sounds.

Dyno testing completed on Mazda 3 and Mazda 6 applications with similar results. Mazda 6 dynograph shown above.
