Category: Extractors and headers


The Pacemaker PH5045_L_R is a set of extractors (headers) listed to fit the 2005–2012 Holden Rodeo and Colorado 3.6L Alloytec. Pipe diameter and material aren't published in this listing.
This is a left-and-right extractor (header) pair that replaces the factory cast exhaust manifolds with tuned primary tubes. On the PH5045_L_R those tubes collect each cylinder's exhaust pulse and merge them at the collector at the front of the exhaust. It's listed for the 3.6L Alloytec engine in the Rodeo and Colorado and covers the manifold section rather than the rear pipework. The pipe diameter and material aren't published by the supplier for this listing.
Extractors are an engine-back change. The trade-off is character and effort: a tuned set can free up exhaust flow off each cylinder compared with a restrictive cast manifold, but the tubes sit close to the engine and are more involved to fit than a bolt-on muffler, and the note can shift louder than stock. This set is built for the 3.6L Alloytec across the 2005–2012 Rodeo and Colorado, so it's listed against the specific engine and era rather than the badge alone — engine and body determine which header set lines up correctly.
It's listed to fit the 2005–2012 Holden Rodeo and Colorado with the 3.6L Alloytec. Feed data can be imperfect, so confirm your engine, year and body with the workshop before ordering — the Alloytec listing here is specific to that engine across this period.
Oak Flats Muffler Men supplies and fits extractor sets like the PH5045_L_R in-house across the Illawarra. Headers sit tight to the engine, steering and chassis, so we check clearances, gaskets and sensor bungs before the hoist. It's listed at $789.22 RRP and is typically a special-order item, so send your registration or build details and we'll confirm the part and lead time. On emissions: headers change the manifold section, so road compliance depends on your state's requirements — confirm what's needed for NSW registration with us before fitting.
