Why Choose Wildcat Headers?

Wildcat Headers (by Genie) are Australian-made and engineered to deliver real-world gains in power, efficiency, and throttle response. Originally press-bent, most of the range is now mandrel-bent for improved flow and precision. Press-bent pipes remain highly durable, as the metal is not stretched as aggressively during bending.
