Two Everflo mufflers, no resonator — that's the character of this kit (HOLDEN-COMMODORE-VT-VY-V6-UTE-WAGON-2-1-2-CATBACK-KIT-INC-2-X-EVERFLO-MUFFLERS), a 2in cat-back for the VT–VY V6 Holden Commodore ute and wagon. Running a muffler at the mid and another at the rear keeps the note subdued through the whole back section.
What does running two mufflers do?
Both quietening stages here are Everflo mufflers — absorptive/chambered units that soak up sound rather than just resonate a frequency. A second muffler in the line gives a more thoroughly damped, quieter result than a single muffler or a muffler-plus-resonator pairing. For a V6 ute or wagon that's the calmer, more conservative tune of the cat-back options.
Where does a 2in cat-back sit in the system?
A cat-back is everything from the catalytic converter back. This one is sized at 2in for the V6 and finishes through the two Everflo mufflers. It leaves the converter and front of the system in place and focuses on the rear flow path and note.
Does it suit a ute or a wagon?
It's listed to fit the Holden Commodore VT–VY V6 in both ute and wagon body styles. The two share much of the rear floor across this range, but confirm your exact model and year with the workshop so the routing matches your car.
What happens when we fit it?
Oak Flats Muffler Men fits Commodore cat-backs like this in-house across the Illawarra. We hang both mufflers, set the rear clearances and check the tailpipe exit before sign-off. Send your build and we'll confirm the kit suits your VT–VY.
