Holden 2005 - 06 CV8Z Monaro Duel Outlet Try-Y Headers 2 1/2 Inch System.
Category: Extractors and headers


The Pacemaker PP5367-09 is a Tri-Y header set with a dual-outlet 2-1/2 inch system, listed to fit the 2005-06 Holden CV8Z Monaro. It's a header-and-pipework package, not a tailpipe-only swap.
This is a Tri-Y extractor design paired with a dual-outlet 2-1/2 inch system, listed for the CV8Z Monaro from 2005-06. Tri-Y refers to how the primary pipes pair off before merging — a layout chosen to keep mid-range pulses tidy on a V8 like the Monaro's. The dual-outlet rear means the system splits to two exits rather than one. No flow, power or sound figures are published by the supplier, and we won't quote any.
Headers (extractors) replace the cast factory exhaust manifolds with tuned tubular primaries. The idea is to give each cylinder a cleaner path out, which is why enthusiasts fit them as the front end of a performance exhaust. They sit right at the engine, so fitment tolerances and clearances around the bellhousing and steering matter. What a set like this actually delivers on your car depends on the rest of the system and the tune — we don't publish numbers for it.
It's listed to fit the Holden CV8Z Monaro from 2005, and the dual-outlet 2-1/2 inch layout is specific to that build. Header fitment is tight by nature, so confirm your exact variant and any prior modifications with the workshop before ordering.
Oak Flats Muffler Men fits Tri-Y header systems like this in the Illawarra. We check primary and collector clearance, fit fresh gaskets, and confirm the dual-outlet system lines up with your Monaro before sealing it for heat. RRP is listed at 4406 AUD; fitting is quoted once we've seen the car.
