Holden 2001 - 2005 CV8 Monaro Single Outlet Try-Y Headers 3" Inch System (SKU: PP5367-57), $4301.19 from Pacemaker.
Category: Extractors and headers


The Pacemaker PP5367-57 is a 3in Try-Y header system listed to fit the Holden Monaro CV8 built 2001–2005, in single-outlet form. It's a full extractor-and-pipework package rather than a tip swap, priced at $4,301.19 AUD.
This PP5367-57 runs Pacemaker's Try-Y header design into a 3in system sized for the V8 Monaro. A Try-Y header gathers the primaries into a stepped collector arrangement before the pipe rather than dumping straight into a single merge, which is the part of the exhaust closest to the heads and the section most builders change first. It's set up here as a single-outlet layout, so the rear of the system feeds one exit path.
Headers (extractors) replace the cast factory manifolds with tubular runners. A Try-Y is a specific collector geometry that pairs cylinders into Y-junctions to manage exhaust pulses on a V8. The trade-off is honest: headers and a larger 3in system change how the engine breathes and how it sounds compared with stock, and they shift where emissions hardware sits, so they're a considered upgrade, not a bolt-on accessory. We don't publish power or sound figures for this part — Pacemaker doesn't supply them and we won't invent them.
It's listed to fit the 2001–2005 Holden Monaro CV8 in single-outlet configuration. Listings can be imperfect, so confirm your exact build — engine, gearbox and any prior modifications — with the workshop before ordering. A header set this size is a special-order item at this price point, so we check fitment first.
Oak Flats Muffler Men supplies and fits Pacemaker header systems in-house across the Illawarra. For a 3in Try-Y package we check clearances, the collector-to-pipe joins and any compliance requirements for your registration before booking the bay. Road compliance for header changes is something we confirm with you up front rather than assume.
