Category: Mufflers and resonators


The Pacemaker KB8500-XCMX is a single 3in exhaust kit listed to fit the Isuzu D-Max 3L 4JJ1 turbo-diesel built July 2008 to July 2010, supplied with a catalytic converter and a muffler. The with-cat build is the defining choice — it keeps the emissions hardware for the early 4JJ1 D-Max.
This kit includes a catalytic converter, so the emissions equipment the 4JJ1 D-Max needs for road compliance stays in the system. On a diesel ute that converter is the line between a road-minded build and an off-road one. The KB8500-XCMX pairs the cat with a muffler to keep the note civil, making it the registration-friendly option of the pair. Confirm your state's requirements with the workshop before fitting.
At a 3in bore, this kit steps up from a tighter stock system for the 3L 4JJ1 turbo-diesel of the July 2008 to July 2010 D-Max. As a single 3in kit it runs one larger pipe through the cat and muffler — a complete section rather than a single replacement part. The 3in figure is the hard number here; material isn't published, so we won't claim stainless or aluminised.
It's listed to fit the Isuzu D-Max 3L 4JJ1 turbo-diesel built July 2008 to July 2010. Confirm your exact ute, its engine and current exhaust with the workshop before ordering so the 3in kit, cat and muffler line up with the factory hardware.
