This twin 2in kit (HOLDEN-COMMODORE-VT-VZ-V6-V8-SEDAN-TWIN-2-1-2-KIT-INC-XPIPE-EVERFLO-MUFFLERS-HOT) is the X-pipe build for the Holden Commodore VT–VZ sedan with Everflo mufflers and hotdog rears. The mix is the point: Everflo mufflers carry the main silencing, with compact hotdog resonators at the rear.
What's the muffler-plus-hotdog-rears layout?
This kit pairs Everflo mufflers with hotdog resonators at the back. The Everflo mufflers do the main silencing through the body, while the hotdog rears — compact straight-through resonators — tune the tail end without choking flow. Combining the two is a deliberate split: chambered silencing where it does the most work, free-flowing resonators at the rear for the final note.
Why a twin 2in kit with an X-pipe?
On a 2in bore this is the twin layout for the VT–VZ sedan, running two banks of pipe down the car. Supplied by Exhaust Systems Australia as a complete kit, it includes the X-pipe that crosses the two banks so they share pulses and even the note out — the reason an X-pipe sits in a dual system rather than two separate pipes. It's listed for V6 and V8, with the sedan floorpan setting the routing.
Will it suit my VT–VZ sedan?
It's listed to fit the Holden Commodore VT–VZ V6 and V8 sedan. The twin routing and hanger points are particular to the sedan body. Confirm your exact model and engine with the workshop before ordering so the kit lines up with your car.
