Twin hotdogs define this kit (HOLDEN-COMMODORE-VY-SERIES-II-V6-SEDAN-2-1-2-CATBACK-KIT-INC-2-X-HOTDOGS): a 2in cat-back for the VY Series II V6 Holden Commodore sedan that uses two straight-through resonators instead of a conventional muffler, for a freer-flowing path with a harder edge to the note.
What does running two hotdogs do to the sound?
A hotdog is a compact straight-through resonator — a perforated core in packing that lets gas pass with little restriction while damping select frequencies. Using two of them in place of a chambered muffler keeps the flow path open and gives a louder, more open note than a muffler-based kit. It's the more vocal of the VY sedan cat-back options here, so it suits an owner chasing presence over a quiet cabin.
What is a cat-back on a VY sedan?
The cat-back is the section from the catalytic converter rearward, here at 2in for the V6. It leaves the front pipe and emissions hardware as they are and changes the flow and tone through the back of the car — exactly where two straight-through hotdogs make their mark.
Will it suit my VY Series II sedan?
It's listed to fit the Holden Commodore VY Series II V6 in sedan form. The Series II is a specific build within the VY range, so confirm your exact model and year with the workshop before ordering so the routing matches.
How do we fit it in the Illawarra?
Oak Flats Muffler Men supplies and fits this kit in-house. With two hotdogs in line we set the resonator positions for floor and axle clearance, align the hangers and check the tailpipe exit before sign-off. Send your build and we'll confirm it suits your VY Series II.
