Pacemaker HSV VE (E Series) E2 From Sep 2009 - Aug 2010 LS2 V8 1 3/4 Tri-Y Headers 2 1/2 Inch System.
Category: Extractors and headers


The Pacemaker PP5387-03 runs 1-3/4in primary tubing into a 2-1/2in system, and that primary size is the story: it keeps gas speed up for street-engine response on the HSV VE E-Series E2 (Sep 2009 to Aug 2010) with the LS2 V8.
Primary bore is an application choice. A 1-3/4in primary keeps exhaust gas velocity high through the runners, which favours low and mid-range pull on a road-driven LS2 rather than chasing peak flow for a high-rpm build. Matched to a 2-1/2in system behind it, the PP5387-03 is sized for a car that lives on the street, not a strip-only combination.
This set is listed to a tight build window — the VE E-Series E2 from Sep 2009 to Aug 2010 — because HSV stepped the VE through E1, E2 and E3 with detail changes. The E2 qualifier is what ties this part to your car, so it matters more here than on a broadly-listed header. Headers like this bolt to the cylinder heads in place of the cast factory manifolds and form the front section the rest of the exhaust follows.
The PP5387-03 uses a Tri-Y merge, pairing the primaries in two stages rather than a single four-into-one. Combined with the 1-3/4in primaries, that reinforces the broad torque character rather than a peaky top end. Pacemaker doesn't publish material or sound figures for this part, so we don't quote any.
Oak Flats Muffler Men supplies and fits this Pacemaker package in-house across the Illawarra. Header work on the LS2 means manifold removal, fresh gaskets and clearance checks against the 2-1/2in system. Treat the E2 listing as listed to fit rather than guaranteed, send your build, and we'll verify it to your HSV and book the hoist. The listed RRP is $4773.96.
