Nissan Patrol ZD30 GU 3.0 CR Wagon Without Cat CEN MUF (MKNI0049) Fits NISSAN. Fast shipping, warranty included.
Category: Complete exhaust systems


Listed at $1374.07, the MPI Automotive MKNI0049 is a without-cat exhaust for the Nissan Patrol GU wagon running the 3.0 ZD30 common-rail engine. It carries a centre muffler in the run.
This is a full system for the ZD30 common-rail Patrol GU wagon that deletes the catalytic converter while keeping a centre muffler in the line. The muffler is the difference against the bare-pipe versions of this Patrol listing: it keeps the centre silencing, so the tone is steadier than a fully open run. MPI Automotive doesn't publish the bore or material for this listing, so neither is quoted here and both are confirmed against the wagon at fit-up.
Removing the converter takes a major restriction out of the line, while leaving a centre muffler in place keeps some of the standard silencing so the note lifts without going fully open. For a GU wagon owner that's the middle of MPI's ZD30 range — a clearer tone than standard, but more composed than the bare-centre option. It's a flow-and-sound change, not a tune, and how it suits depends on how the Patrol is used.
Because the MKNI0049 deletes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. Keeping the centre muffler doesn't change that — the missing cat is the issue. If you want a registrable build for the GU wagon, ask the workshop about a with-cat alternative before ordering.
Oak Flats Muffler Men supplies and fits the MKNI0049 across the Illawarra. We confirm the ZD30 GU wagon fitment, check the centre muffler position and the hanger points on the hoist, then bring the spec in through MPI Automotive once your exact build is confirmed.
