This is the twin X-pipe-and-hotdogs kit finished with its own tailpipe: the HOLDEN-COMMODORE-VT-VZ-V6-V8-SEDAN-TWIN-2-1-2-KIT-INC-XPIPE-EVERFLO-HOTDOGS-TAIL from Exhaust Systems Australia is a twin 2in system with an X-pipe crossover, Everflo hotdogs and a matching tailpipe section. It's listed to fit the Holden Commodore VT–VZ V6 and V8 sedan.
What does this twin kit include?
It's the complete twin layout: dual 2in pipes crossed by an X-pipe so the two banks equalise, Everflo hotdogs to trim resonance, and a matching tailpipe to finish the exit. Including the tailpipe means the rear of the system is supplied as one section rather than sourcing the exit separately. The hotdogs are compact straight-through resonators, so the silencing stays light and the system free-flowing across both pipes.
How does the X-pipe shape the note?
The X-pipe links the two sides at one crossover point, letting the banks balance against each other; on a twin Commodore that tends to smooth the pulses and round the note. Paired with straight-through hotdogs rather than chambered mufflers, the result is an open rather than subdued character. We can't put a number on the sound — there's no dB data — so the honest test is to hear a comparable VT–VZ twin fit before you commit.
Will it suit my VT–VZ sedan?
It's listed to fit the Holden Commodore VT through VZ V6 and V8 sedan as a twin system. The dual routing, X-pipe and tailpipe positions and hanger spacing are specific to that sedan body, so confirm your exact model and driveline with the workshop before ordering to make sure this kit is the right one for your car.
How do we fit it at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this twin kit in-house across the Illawarra. We set the X-pipe crossover square, mount the Everflo hotdogs on the sedan hangers and line the tailpipe up at the rear, checking clearance on both sides. Bring the car in and we'll confirm fitment and book the bay.
