Nissan Patrol GU 3.0 Ute Without Cat Centre WOM.
Category: Complete exhaust systems


The MPI Automotive SSMKNI0039 is an exhaust system listed to fit the Nissan Patrol GU 3.0 ute, supplied without the catalytic converter and with the centre muffler deleted. At an indicative RRP of $1,800.36, this cat-delete build is an off-road-only part.
It's listed to fit the cab-chassis Nissan Patrol GU 3.0 ute. The ute body routes its exhaust differently to the wagon, so this carries its own part number — send us your exact build and we'll confirm it before ordering, since the GU ran for years and the listing can be imperfect. MPI Automotive publishes no system type, diameter or material for it, so we don't quote those.
This listing leaves out both the catalytic converter and the centre muffler. Deleting the centre muffler takes a silencing stage out of the run — a sound and packaging decision, with no published sound figure to quote. Removing the cat is the emissions change that sets the road-legal position below.
Because the SSMKNI0039 deletes the catalytic converter, it is not ADR 79/04 compliant for road registration in NSW and is for off-road use only. The cat is the emissions hardware that keeps the Patrol road-legal, so this build sits firmly in off-road territory.
Oak Flats Muffler Men fits Patrol systems in-house across the Illawarra. As a special-order part we confirm the ute fitment and current pricing with MPI Automotive first, check clearances on the hoist, and only fit cat-delete systems for off-road use.
