Holden Trailblazer 2.8L Turbo Back With Cat & Muffler.
Category: Mufflers and resonators


The MPI Automotive MKHN0349 is a turbo-back for the Holden Trailblazer 2.8L that keeps the catalytic converter and runs a rear muffler. Cat retained, muffler fitted — the road-minded engine-back build for the wagon.
A turbo-back replaces the exhaust from the turbo outlet rearward — a longer span than a cat-back and the section where a 2.8L diesel like the Trailblazer's tends to free up. The MKHN0349 keeps the catalytic converter and finishes through a rear muffler, so it's the engine-back upgrade rather than a tailpipe-only change, with the factory emissions hardware left in place.
Retaining the catalytic converter holds the emissions component that usually governs registration on a diesel wagon, and keeping the rear muffler holds the chambered box that keeps the note civil. Together they make the MKHN0349 the more liveable, road-oriented turbo-back build — bigger flow than stock without stripping out the components a delete system removes.
Because the MKHN0349 keeps the catalytic converter, it leaves the emissions component that usually decides registration on a diesel vehicle in place. Compliance still depends on the full vehicle, noise rules and your state's requirements, so confirm the exact build and any NSW conditions with the workshop before fitting.
It's listed to fit the Holden Trailblazer 2.8L; the supplier names the engine but not the exact years, so confirm your variant with us. We fit the MKHN0349 in-house across the Illawarra, checking the cat, muffler and the routing from the turbo back for clearance as it goes up.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
