The MPI Automotive HOLK128-134C-GTS pairs 1-3/4in coated headers with a dual 3in full system, listed to fit the Holden VF HSV GTS LSA V8 sedan and wagon. It works from the heads back, built around the supercharged V8's primaries rather than the tailpipe alone.

What does this package cover?

This listing combines 1-3/4in coated headers with a dual 3in full system, spanning the exhaust from the cylinder heads rearward. The 1-3/4in figure is the primary-tube diameter where the headers meet the LSA V8, and the dual 3in is the twin pipework behind them. It's listed for the VF HSV GTS in sedan and wagon forms, with the header tubes carrying a coating.

What are coated headers and what do they change?

Headers, also called extractors, replace the cast factory manifolds with tuned tubular primaries that merge downstream. The coating is a surface treatment on the tubes, typically used to manage under-bonnet heat. They sit at the front of the system, so the geometry they set governs everything behind. This set differs from the 1-7/8in version only in the slightly smaller primary tube. We hold no flow, power, boost or sound figures and won't quote any — the honest spec is the 1-3/4in tube size, the dual 3in system and the coated finish, each traceable to the listing.

Will it suit my HSV GTS sedan or wagon?

It's listed to fit the Holden VF HSV GTS LSA V8 in sedan and wagon body styles. The two bodies differ behind the cabin, so your exact build, year and driveline decide the fit. Confirm your car against the listing with the workshop before ordering; we check the body style rather than assume it.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men fits coated-header packages like this in-house across the Illawarra. We remove the cast manifolds, fit the 1-3/4in coated headers on fresh gaskets, hang the dual 3in system and check clearances along the run on a supercharged V8 that runs hot. RRP is listed at 6306.95 AUD; fitting is quoted once we've seen the car.
