Mitsubishi Challenger PB/PC 2.5L (4D56T) 2009-2015 Manual - Single 3" Exhaust System with Cat, Muffler and Resonator (KB9200-XCMR) at $1867.20 RRP.
Category: Mufflers and resonators


The Pacemaker KB9200-XCMR is a single 3in exhaust system listed to fit the manual Mitsubishi Challenger PB–PC 2.5L 4D56T turbo-diesel (2009–2015), supplied with a catalytic converter, a muffler and a resonator. The with-cat, resonator-and-muffler build is the defining feature — it keeps the emissions hardware and adds a resonator for drone control.
This system includes a catalytic converter, so the emissions equipment the 4D56T Challenger needs for road compliance stays in place. On a diesel that converter is the line between a road-minded build and an off-road one. The KB9200-XCMR is the road-minded option, pairing the cat with both a muffler and a resonator. Confirm your state's requirements with the workshop before fitting.
Beyond the muffler, this system carries a resonator — a tuning device that targets a specific frequency to cut drone without a broad change in volume. On a diesel wagon that's about keeping the cabin liveable at cruise. So the muffler handles general quietening and the resonator chases the boom, a more resolved setup than a muffler alone. No decibel figures are published, so we won't quote any.
At a 3in bore, this is sized up from a tighter stock system for the 2.5L 4D56T. It's listed specifically for the manual Challenger, which sets the routing around the gearbox and crossmember. The 3in figure is the hard number; material isn't published, so we won't claim stainless or aluminised. Confirm your exact Challenger and that it's the manual with the workshop before ordering.
Oak Flats Muffler Men supplies and fits the KB9200-XCMR in-house across the Illawarra. We check the 3in routing under the Challenger, confirm the cat, muffler and resonator positions and clearance, and fit the system as a complete section. Send your build and we'll confirm and book the bay.
