Holden Trailblazer 2.8L Turbo Back Without Cat & With Muffler (SKU: MKHN0350) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive MKHN0350 is a turbo-back system for the Holden Trailblazer 2.8L that deletes the catalytic converter and runs a rear muffler. Being turbo-back, it replaces the exhaust from the turbo outlet rearward — the full engine-back span, not a tailpipe-only change.
A turbo-back run starts at the turbo outlet and replaces everything behind it, which is the longest section you can change on a diesel like the Trailblazer's 2.8L and where the bigger-bore step does its work. The MKHN0350 finishes through a muffler, so it keeps a chambered silencer at the rear to temper the note rather than running wide open. It's the comprehensive build for owners reworking the whole exhaust in one go.
No — the MKHN0350 deletes the catalytic converter, so it is not ADR 79/04 compliant for road registration in NSW and is intended for off-road or competition use only. Removing the cat takes out emissions hardware the Trailblazer was registered with; that's a firm line, not a caveat. Discuss how the vehicle will be used with the workshop before committing.
It's listed to fit the Holden Trailblazer 2.8L. The 2.8L turbo-diesel routing and the wagon's underbody set the run, so the engine and body both matter. Confirm your exact build with the workshop before ordering, as feed data can be imperfect.
Oak Flats Muffler Men supplies and fits the MKHN0350 in-house across the Illawarra. We confirm the cat-delete suits how the Trailblazer will be used, check muffler and pipe clearance under the body, and hang the turbo-back run square. Bring it in and we'll confirm fitment and book the bay.
