Cat retained, muffler deleted — that's the trade the MPI Automotive MKHN0470 makes. It's a turbo-back for the 2.8L Holden Trailblazer that keeps the factory catalytic converter for road compliance while running without a muffler, so it flows harder than a muffled build but stays registration-minded.

What does keeping the cat but dropping the muffler give you?

The MKHN0470 holds onto the factory catalytic converter — the emissions hardware that matters for road compliance on a diesel wagon — but deletes the muffler. So there's no absorptive element in the run to soften the note, and the path is freer than a muffled version, yet the cat stays where the factory had it. It's the build for a Trailblazer owner who wants a harder character without changing the vehicle's emissions side. Confirm any state requirements with the workshop before fitting.

Where does the turbo-back start on the Trailblazer?

A turbo-back runs from the turbo outlet rearward, the longest single span short of a custom system, and on a 2.8L diesel it's where the most pipework frees up. Retaining the cat keeps the emissions equipment as standard while the deleted muffler opens the tone. The MKHN0470 carries a published RRP of $1,755.05.

Common questions

Does the MKHN0470 keep the catalytic converter?
Yes — this is the with-cat turbo-back, so the factory catalytic converter stays in place. Confirm any state requirements with the workshop before fitting.
How does deleting the muffler change the note?
With no muffler in the run there's no absorptive damping, so flow is freer and the note more present than a muffled version. We don't publish decibel figures.
