Isuzu DMAX 4JJ3 Exhaust

Isuzu DMax 4JJ3 Exhaust system is a 3.5-inch DPF back exhaust for the Turbo diesel 4JJ3

This is a 3.5-inch Stainless steel system that bolts directly to the DPF and replaces the standard exhaust.

This is a 3/4 length exhaust that finishes at the diff. This gives the most potential exhaust note with the DPF in place and allows for a large spare tire without it hitting on the exhaust

This system is hand-made in-house by KM- Kuluin Mufflers. We are located on the Sunshine Coast Qld and specialize in Custom Exhaust Fabrication. All of our products are Australian-made and created from the highest quality locally sourced components. Our fabrication team takes pride in the products we make to ensure our customers are 100% satisfied with their exhaust.
