Holden Commodore V8 Tri Y design 1 5/8Inch Header & Cat Kit Special order item for Xforce - Holden.
Category: Extractors and headers
The Exhaust Systems Australia HOLDEN-COMMODORE-V8-TRI-Y-DESIGN-1-5-8INCH-HEADER-CAT-KIT is a tri-Y design header and cat kit listed to fit the Holden Commodore V8. It runs a 1-5/8inch primary and is a special-order item.
Headers, also called extractors, replace the cast factory manifolds with tubular runners from each cylinder. A tri-Y design pairs the runners in stages before they collect, a layout chosen for how the pulses combine. This kit pairs those tri-Y headers with a catalytic converter section, covering the front of the system and the cat as one matched set for the Commodore V8.
This kit runs a 1-5/8inch primary, the header tube size in its part number, with the catalogue diameter on record reading 8in for how that size is coded on these kits. Because the cat is part of the kit, the emissions component is included rather than deleted; road compliance still depends on the correct parts for your car, which the workshop confirms. The material isn't published in the listing.
It's listed to fit the Holden Commodore V8. Confirm your exact model and engine with the workshop before ordering, since a header-and-cat kit is a significant fitment that needs to match the car. As a special-order item it's brought in to order, so plan the timing in.
