04 - 06 MAZDA 3 - 2.0 Header

04 - 06 MAZDA 3 - 2.0 Header

Exhaust Header has been designed to improve exhaust flow leaving the cylinder head with fewer restrictions.

This 4-2-1 exhaust header achieves this better flow by increasing the size of the header piping and removing the power-robbing catalytic converter. This increased flowing ability results in more horsepower and torque that the engine can produce. Throttle response is also improved at all RPM ranges.

Each header is made from high quality stainless steel and is mandrel bent to reduce exhaust obstruction. The Mazda Exhaust Header bolts perfectly to the cylinder head using existing hardware and includes bungs for existing OEM sensors. The exhaust header will bolt to your existing factory exhaust or other aftermarket exhaust system for an OEM-like fitment.
