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.

What does a turbo-back cover on the Trailblazer?

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.

Why keep both the cat and the muffler?

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.

Is it road legal?

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.

Common questions

Does the MKHN0349 keep the catalytic converter?
Yes. It's the with-cat, with-muffler turbo-back, so the factory cat stays in place.
Is it a quiet system?
It runs a rear muffler, so it's the more subdued, road-oriented turbo-back build rather than a loud one.
Will it fit my Trailblazer?
It's listed to fit the Holden Trailblazer 2.8L. Confirm your exact year and variant with the workshop before ordering.
