This kit runs a rear tailpipe rather than a rear muffler — the more open of the two cat-back builds. The Exhaust Systems Australia HOLDEN-COMMODORE-VN-VS-V8-SEDAN-2-1-2-CATBACK-KIT-CENTRE-HOTDOG-WITH-REAR-TAILPI is a 2½in cat-back kit with a centre hotdog, listed to fit VN–VS Commodore sedans.
What does the rear tailpipe layout change?
Instead of finishing in a rear muffler, this kit runs the centre hotdog through to a rear tailpipe. With the only silencing device being the straight-through hotdog mid-pipe, the rear is left more open, so it's the louder, freer-flowing of the two cat-back options. Choose this one if you want the V8 to carry more voice out the back rather than be tucked away by a rear muffler.
What's in the 2½in cat-back kit?
It's a full rear-section kit in 2½in: a centre hotdog resonator and a rear tailpipe to replace the system from the catalytic converter back. The cat and front of the exhaust stay as fitted. The listing spans VN–VS sedans, with the VN–VR V6/V8 and VS V8-only fitment named in the title — the workshop will confirm which suits your car.
Will it suit my Commodore?
It's listed to fit the Holden Commodore VN–VS V8 sedan, with the broader VN–VR V6/V8 and VS V8-only fitment in the title. At $250 RRP it's the keener-priced cat-back of the pair. Send your model and engine to the workshop to confirm before ordering.
How does Oak Flats fit it?
Oak Flats Muffler Men supplies and fits these kits in-house across the Illawarra. We set the centre hotdog, route the rear tailpipe for clearance, and confirm the hangers and joins seal. If the open rear is louder than you want for daily driving, ask about the rear-muffler version instead.

Common questions
How is this different from the rear-muffler version?
This kit runs a rear tailpipe instead of a rear muffler, leaving the rear more open and louder. The only silencing device is the straight-through centre hotdog.
Is it louder than the muffler kit?
With no rear muffler and only a straight-through hotdog mid-pipe, the rear is freer-flowing, so it carries more sound than the muffler version. We can't quote a dB figure.
Does it fit a VN–VS Commodore?
It's listed for VN–VS sedans (VN–VR V6/V8 and VS V8-only as noted). Confirm your model and engine with Oak Flats Muffler Men before ordering.
