What makes the SSMKNI0070 quieter than the hotdog versions?

It uses two chambered mufflers (centre and rear) rather than a muffler plus a free-flowing hotdog resonator, so silencing happens at two stages for a more subdued note.

Is it a full exhaust or just the rear?

It's a full system, replacing the exhaust along its whole length for the Patrol GU 4.8L. Confirm the exact scope for your build with the workshop.

What pipe size is it?

The supplier hasn't published a diameter for this listing. We confirm the bore on the physical part.

The MPI Automotive SSMKNI0070 is a full system for the Nissan Patrol GU 4.8L running twin mufflers — one centre, one rear. That dual-muffler layout is its defining trait: two chambered silencers in series, aimed at the most subdued, controlled note across the whole length of the 4.8L petrol GU's exhaust.

Why two mufflers instead of a muffler and a hotdog?

Pairing a centre muffler with a rear muffler — rather than a muffler then a hotdog resonator — is the quieter-leaning choice. Both units are chambered silencers working by absorption and reflection, so volume is reduced at two stages instead of one stage plus a free-flowing resonator. On a 4.8L petrol straight-six like the GU's, that's the setup for owners who want a tidy, restrained note over a louder, freer one.

What does a full system cover?

A full system replaces the exhaust along its entire length rather than just the rear, so it's the comprehensive job when the original GU pipework is worn front to back. The supplier hasn't published a pipe diameter for this listing, so we confirm the bore on the actual part instead of quoting a number we can't verify. What's certain from the listing is the dual-muffler arrangement across the complete run.

Will it suit my Patrol GU 4.8L?

The SSMKNI0070 is listed to fit the Nissan Patrol GU with the 4.8L engine. As a full-length system, the routing and every hanger need to suit your exact build, so send your details through and we'll confirm the path before ordering.
