Exhaust Systems Australia Commodore VT-VZ Sedan XFORCE Twin 2.5" Catback Exhaust Raw 409 - Hotdog Rear Special order item.
Category: Mufflers and resonators
This XForce-style twin 2.5in cat-back for the Holden Commodore sedan (VT-VZ) finishes on a hotdog rear — a compact straight-through resonator rather than a chambered muffler — so it flows freely and trims drone without heavy muffling. Supplied by Exhaust Systems Australia in raw 409 stainless as a special-order item.
A hotdog is a short straight-through resonator: a perforated core in packing, with no baffles to bend the flow. As the rear element of this cat-back it keeps the system free-flowing and knocks back harsh frequencies and drone rather than muffling heavily. The result is a louder, freer character than a chambered rear box — the choice for owners who want flow and note over maximum quiet.
It's a cat-back run in a twin 2.5in layout, replacing the system from behind the catalytic converter rearward. The cat and the hardware ahead stay in place, so this is the rear-system upgrade for the sedan, sized at 2.5in for a balance of flow and street manners on the Commodore.
Construction is 409 stainless in a raw, unpolished finish — a corrosion-resistant grade without a mirror polish. As a special-order item it's built or brought in to order, so confirm lead time with the workshop before committing.
It's listed to fit the Commodore sedan across VT to VZ. Oak Flats Muffler Men fits hotdog cat-backs like this in-house in the Illawarra. Exhaust Systems Australia lists it at $965; confirm your exact build and the special-order lead time with us before ordering.
