The Pacemaker KB9511-HCMR is a 2-1/2in exhaust system with headers, a cat, a muffler and a resonator, listed to fit the Nissan Patrol GU TB48DE 4.8L 6-cylinder petrol from 2001 to 2010. It's a header-back package that changes the exhaust path from the manifolds rearward.
What does this system cover?
KB9511-HCMR bundles headers off the TB48DE inline-six, a catalytic converter, a muffler and a resonator into a 2-1/2in system for the GU Patrol. The headers replace the cast manifolds at the front, the cat keeps the emissions hardware in the line, and the muffler-plus-resonator combination handles the note down the back. Supplied as one package, the diameter step and joins are matched for the 4.8L petrol Patrol rather than mixed from separate parts.
What's a header-back system with a resonator and what does it change?
This runs from the headers rearward and includes both a muffler and a resonator. A resonator is a secondary chamber that targets specific frequencies, often used alongside the main muffler to keep a system civil rather than droning. The trade-off versus a single-muffler system is more silencing hardware in the run. We hold no sound figures, so we won't quantify the note — the honest description is a 2-1/2in header-back system with cat, muffler and resonator for the GU Patrol.
Will it suit my Nissan Patrol GU?
It's listed to fit the Nissan Patrol GU with the TB48DE 4.8L 6-cylinder petrol from 2001 to 2010. Fitment listings can be imperfect, so confirm your exact build and engine with the workshop before ordering, especially if the Patrol has had prior exhaust work. Recommended retail is $2,314.05.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits header-back systems like this in-house across the Illawarra. We fit the headers at the TB48DE's head, install the cat, then hang the 2-1/2in pipework with the muffler and resonator back to the rear. Send your GU Patrol's details and we'll confirm clearances and book the bay.
