Will the KB9511-CB-MR make my Patrol loud?

It runs both a muffler and a resonator, so it is tuned to settle the TB48 petrol six rather than shout. Expect a fuller-than-stock but refined note.

Does it fit the whole GU run?

It is listed to fit the GU Patrol TB48DE 4.8L petrol from 2001 to 2010. Confirm your exact series with the workshop before ordering.

Yes — Pacemaker builds this cat-back at 2in, sized for the standard or lightly worked TB48 rather than a big modified engine.

Pairing a muffler with a resonator, the Pacemaker KB9511-CB-MR is a 2in cat-back listed to fit the Nissan Patrol GU with the TB48DE 4.8L six-cylinder petrol (2001–2010). The two-silencer layout is built to settle the big petrol six rather than chase volume.

What does the muffler-and-resonator pairing achieve?

Running a muffler and a resonator together splits the work: the muffler absorbs broad volume while the resonator targets the narrower drone frequency, so the combination keeps the TB48 civil across the rev range rather than just at one point. On a smooth-running 4.8L petrol six, that pairing favours a refined, settled note over an aggressive one — a sensible match for a wagon that does highway kilometres.

Why a 2in cat-back on the TB48?

At 2in, this Pacemaker cat-back is sized for the standard or lightly worked TB48DE rather than a heavily modified build, prioritising a clean, free-breathing replacement of the factory cat-back section without going oversize. A cat-back replaces the system from behind the catalytic converter to the tailpipe, leaving the front emissions hardware as it was.

Will it suit my GU Patrol TB48?

It is listed to fit the Nissan Patrol GU with the TB48DE 4.8L petrol across 2001–2010. That covers a long production span, so we confirm your exact GU series and any prior exhaust work before ordering — the listing is a guide, not a guarantee.

Fitting at our Illawarra workshop

Oak Flats Muffler Men supplies and fits this Pacemaker cat-back in-house for Illawarra Patrol owners. We check the hanger positions and joints so the muffler and resonator both sit clear of the chassis and seal properly.
