This is the simplest VY Series II sedan cat-back — a single Everflo muffler and tailpipe: the HOLDEN-COMMODORE-VY-SERIES-II-V6-SEDAN-2-1-2-CATBACK-KIT-INC-EVERFLO-MUFFLER-TAI from Exhaust Systems Australia runs one rear muffler and a matching tailpipe on a 2in body. It's listed to fit the Holden Commodore VY Series II V6 sedan.
What does the single-muffler-and-tailpipe kit cover?
This kit keeps things straightforward: one Everflo rear muffler does the silencing and the matching tailpipe finishes the exit, with no extra resonator or second box. As a cat-back it replaces the run from the catalytic converter back — pipe, muffler and tailpipe — so the factory cat and the emissions hardware ahead of it stay in place. It's the cleaner, lower-box-count layout of this family, built on a 2in body to suit the standard Series II six.
When does a one-muffler cat-back make sense?
A single rear muffler with its tailpipe is the practical reset when the back of an older VY system is tired and you want a complete rear section without staging multiple silencers. The Everflo muffler quietens by absorbing and reflecting sound at the tail; we can't put a number on the result — there's no dB data — so the honest test is to hear a comparable VY sedan fit before you commit.
Will it suit my VY Series II sedan?
It's listed to fit the Holden Commodore VY Series II V6 sedan — the Series II spec and the sedan body are the points to confirm, since the ute and wagon and the earlier VY run their own kits. Check your exact build with the workshop before ordering to make sure this single-muffler 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 kit in-house across the Illawarra. We hang the Everflo muffler on the sedan hangers, check clearance to the floor and rear suspension and set the tailpipe square at the back. Bring the car in and we'll confirm fitment and book the bay.
