The dual-outlet rear muffler is the defining feature here: the Exhaust Systems Australia HOLDEN-COMMODORE-VT-VY-V6-V8-ALL-MODELS-2-1-2-REAR-MUFFLER-DUAL-OUTLET is a 2in rear muffler with two outlets, listed to fit VT–VY Commodores across the listed models.
What does a dual-outlet rear muffler give you?
Instead of a single tailpipe, this rear muffler runs two outlets at the back — the twin-tip look that suits the VT–VY Commodore's rear bumper. Mechanically it splits the exit into two pipes, and visually it gives the back of the car the dual-tip presentation many owners want without changing the front of the system. It's the rear silencer with the styling angle built in.
Where does it sit and what bore?
This is the rear unit only, in 2in pipework. It replaces the factory rear muffler and leaves the centre and front of the exhaust as fitted, so it's a targeted rear-section change rather than a full system. The dual outlets handle the tailpipe presentation while keeping the rest of your exhaust intact.
Will it suit my Commodore?
It's listed to fit VT–VY Commodores across the V6/V8 and V6 model ranges named in the title. Send your exact model and engine to the workshop and we'll confirm the rear muffler's connections and the dual-outlet routing suit your bumper before ordering. RRP is $210.
What does fitting involve at Oak Flats?
Oak Flats Muffler Men fits dual-outlet rear mufflers like this in-house across the Illawarra. We mount the unit over the rear, line both outlets up so they sit even in the bumper cut-outs, and confirm the hangers and join seal. As a single rear unit it's a contained job.
