How is the SSMKNI0069 different from the hotdog version?

This one runs two chambered mufflers for a more subdued note, where the hotdog version pairs a muffler with a free-flowing resonator. Both are 2.5in systems off the e-pipe for the Patrol GU 4.5L.

Does it replace the whole exhaust?

No — it runs from the e-pipe back, replacing the rearward section rather than the engine-back pipework. Confirm your setup with the workshop.

What pipe size is it?

It's a 2.5in system, sized for the GU Patrol 4.5L.

The MPI Automotive SSMKNI0069 is a 2.5in system for the Nissan Patrol GU 4.5L that runs twin mufflers — muffler and muffler — taking over from the e-pipe back. Two chambered silencers in series is what sets this one apart: it's the quieter-leaning rear-system choice for the 4.5L petrol GU.

Why a muffler-and-muffler layout?

Running a muffler into a second muffler — rather than a muffler and a hotdog resonator — is the more subdued setup. Both are chambered units that quieten by absorption and reflection, so the system silences at two stages instead of one chambered stage plus a free-flowing resonator. On the GU's 4.5L petrol six, that's the path for owners who'd rather keep the note restrained than open it up. Sound character follows from the layout, not from any figure we publish.

What does the 2.5in bore and e-pipe-back scope mean?

This system is built to a 2.5in diameter, sized sensibly for the GU 4.5L rather than the larger bore you'd choose for a worked engine, and it runs from the e-pipe back. That makes it a rearward system replacement — it flows more freely than a tired factory section without being a full engine-back job, while the twin mufflers keep things quiet through the back half.

Will it suit my GU Patrol 4.5L?

The SSMKNI0069 is listed to fit the Nissan Patrol GU with the 4.5L engine. GU production spanned many years with detail changes to hangers and routing, so send your exact build and we'll confirm the pipe path and the e-pipe join before you order.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits rear systems like this in-house across the Illawarra. We set both muffler positions against your underbody, confirm clearance over the rear axle, and align the hangers so nothing knocks on flex. Book the bay and we'll have it done in one visit.
