Exhaust Systems Australia HOLDEN COMMODORE VT-VY V6 SEDAN 2 1/2" CATBACK KIT INC 2 X HOTDOGS.
Category: Mufflers and resonators
This kit silences with two hotdogs and no big rear muffler: the HOLDEN-COMMODORE-VT-VY-V6-SEDAN-2-1-2-CATBACK-KIT-INC-2-X-HOTDOGS from Exhaust Systems Australia is a 2in cat-back that uses a pair of straight-through hotdog resonators in place of a conventional muffler. It's listed to fit the Holden Commodore VT–VY V6 sedan.
Hotdogs are compact straight-through resonators — gas passes through a perforated core wrapped in absorptive packing — so they trim resonance without choking flow the way a chambered muffler does. Running two of them and skipping a large rear box is the freer-flowing, more open layout of this family: less heavy silencing, more of the V6's own note. We can't put a number on the volume — there's no dB data — so the honest test is to hear a comparable VT–VY twin-hotdog fit before you commit.
Where a muffler quietens by absorbing and reflecting sound in chambers, this kit leans entirely on two straight-through hotdogs, so the silencing is lighter and the system stays freer. It's the choice when you want the cat-back open rather than subdued. As a cat-back it replaces the run from the catalytic converter back, on a 2in body suited to the standard or lightly worked six, with the factory cat left in place.
It's listed to fit the Holden Commodore VT through VY V6 sedan — the single-pipe sedan routing and hanger spacing are particular to that body. Wagons and utes run their own kits, so confirm your exact build with the workshop before ordering to make sure this twin-hotdog kit is the right one for your car.
Oak Flats Muffler Men supplies and fits this kit in-house across the Illawarra. We set both hotdogs along the sedan mid and rear hangers, check clearance to the floor and rear suspension and line the tailpipe up at the back. Bring the car in and we'll confirm fitment and book the bay.
