Category: Mufflers and resonators


Cut specifically for the 4JJ1-TCX D-Max, the Pacemaker KB8500-XXMX is a single 3in kit with a muffler for the Isuzu D-Max 3L turbo-diesel built July 2008 to July 2010. It's the larger-bore upgrade sized for the diesel four, finishing through a muffler to keep the note civil.
This is a single (rather than twin) 3in run supplied as a kit with a muffler. The 3in bore is the bigger-pipe step a turbo-diesel like the D-Max's 4JJ1 tends to free up on, and a single run keeps the routing simple under the ute. The muffler finishes the system so the note stays settled rather than raucous — the usual balance for a daily-driven and worked diesel.
Diesel exhaust kits are cut to a build window because turbo position, mounting and pipework change between models. This one is listed for the Isuzu D-Max 3L (4JJ1-TCX) from July 2008 to July 2010, so the bends and hangers match that era's underbody. Fitting an out-of-window kit risks clearance issues, which is why the date range matters.
Cat fitment isn't published by the supplier for this kit, so whether a catalytic converter is retained is something to confirm with the workshop before fitting. We'll check what your D-Max needs to stay registrable for road use in NSW for your exact build.
Oak Flats Muffler Men supplies and fits diesel exhaust kits like this in-house. We confirm the 3in run clears the chassis rail and crossmember, check the muffler mounting and hangers, and match the kit to your build window. It's listed to fit the 2008–2010 Isuzu D-Max 3L at $1,629 AUD; we verify your exact fitment rather than relying on the catalogue alone.
