XForce 1 3/4" Long Tube Header & 3" Cat System - Holden Commodore VF V8 Bi-Modal - E2-VF82-BIM-KIT

Maximize the performance and sound of your bi-modal equipped VF Commodore V8 with the XForce Header and Cat Kit. This comprehensive system is specifically engineered to bridge the gap between high-performance long tube headers and your factory electronic valve-controlled rear mufflers. Featuring 1 3/4" long tube primaries that transition into 3" outlets and high-flow metallic catalytic converters, this kit optimizes exhaust scavenging for significant power gains. The center section consists of twin 3" hotdog resonators crafted from raw 409 stainless steel, leading to 2.5" diff pipes with ball-flare flanges for a perfect seal against the OEM rear sections. Experience a deeper, more aggressive V8 growl while retaining the functionality of your factory driving modes.
