The XForce E4-HV20-3-CBS is a 2.5in dual catback in 304-stainless, listed to fit the Holden Commodore (VT-VZ), at an RRP of AUD 895. It is the lower-priced of the HV20 dual-2.5 stainless listings we carry.

Will it suit my Holden Commodore?

This part is matched to the Holden Commodore across VT-VZ, and the figure that separates it from its sibling is the price: AUD 895 against the related HV20-2 listing's AUD 965. Listed fitment is a starting point, not a promise across every build in that span, so send your exact model, year and body and we'll confirm it against the E4-HV20-3-CBS before ordering.

What does the listing actually include?

It's a 2.5in dual catback in 304-stainless. The slug also references a 409-stainless catback, so confirm the stainless grade and routing your car needs with us before ordering — the part recorded here is the 304-stainless dual-2.5 system. Muffler configuration beyond that isn't published by the supplier.

Where does a cat-back sit in the system?

A cat-back replaces the rear half of the exhaust from behind the catalytic converter out, here in a dual-2.5 routing. The factory cat and the emissions hardware ahead of it stay in place, so the change is to the rear flow and note — louder than the original system rather than a full engine-back overhaul. 304-stainless is the corrosion-resistant grade chosen for it.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits Commodore cat-backs in-house across the Illawarra. We offer the dual-2.5 system up to your car, confirm both pipes clear and the hangers line up, and book the bay only once the fitment is verified against your build.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
