This twin 2in kit (HOLDEN-COMMODORE-VT-VZ-V6-V8-SEDAN-TWIN-2-1-2-KIT-INC-XPIPE-EVERFLO-MUFFLERS-TAI) is the X-pipe build for the Holden Commodore VT–VZ sedan, finished with Everflo mufflers and tailpipe. It's the muffler-and-tailpipe twin layout — full silencing boxes carried right out to the exit.
What's in this twin muffler-and-tailpipe kit?
Supplied by Exhaust Systems Australia as a complete kit, this build runs two banks of pipe down the sedan and includes the X-pipe, Everflo mufflers and the tailpipe to finish the run. The Everflo mufflers carry the silencing all the way to the exit, and the tailpipe completes the rear — a fully boxed twin system rather than one leaning on rear resonators.
Why a twin 2in kit with an X-pipe?
On a 2in bore this is the twin layout for the VT–VZ sedan. The X-pipe crosses the two banks so they share pressure pulses and the note evens out — the reason a dual system runs an X-pipe rather than two separate pipes. It's listed for V6 and V8, with the sedan floorpan setting the routing for both banks and the rear exit.
Will it suit my VT–VZ sedan?
It's listed to fit the Holden Commodore VT–VZ V6 and V8 sedan, with the twin routing and hanger points particular to the sedan body. Confirm your exact model and engine with the workshop before ordering so the kit lines up with your car.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits twin kits like this in-house across the Illawarra. We align both banks, seat the X-pipe square, hang the Everflo mufflers level, set the tailpipe so it exits cleanly, and check floor and tunnel clearance the length of the car. Bring it in and we'll confirm the build and book the bay.
