The Exhaust Systems Australia HOLDEN-COLORADO-TWIN-CAB-RC-2008-2011-D-MAX-TURBO-DIESEL-3-0L-3-409-TURBO-BACK-S is a 3in 409 turbo-back system listed to fit the Holden Colorado twin-cab RC (2008–2011) and the Isuzu D-Max with the 3.0L turbo-diesel. It comes with a cat dump and is a special-order item.
This is a turbo-back run for the RC Colorado and D-Max twin-cab, replacing the exhaust from the turbo outlet rearward at a 3in bore in 409 stainless. The listing includes a cat dump as part of the front section, so it covers the engine-back span rather than just the rear pipe.
A turbo-back system replaces the exhaust from the turbo outlet rearward — a longer span than a cat-back and the point where a forced-induction engine tends to free up. It takes in the section between the turbo and the tailpipe, so it's an engine-back upgrade rather than a tailpipe-only swap. On a 3.0L turbo-diesel ute like the RC Colorado, that's the bigger-bore step from the turbo back at 3in, with the cat dump handling the front of the run.
It's listed to fit the Holden Colorado twin-cab RC from 2008 to 2011 and the Isuzu D-Max with the 3.0L turbo-diesel. As a special-order item, confirm your exact model, year and engine with the workshop before ordering — fitment data can be imperfect.
This is a turbo-back diesel system and the supplier hasn't published the emissions detail for it, so road-compliance specifics are something to confirm rather than assume. Check the build and any NSW registration requirements with the workshop before fitting so you know exactly what's going on the ute.
