Configured as a dual 2.5in cat-back with a rear muffler and tailpipe, the MPI Automotive SSMKHN0147 is listed to fit the Holden VX-VY V8 Monaro. It's the muffler-and-tailpipe build of the dual Monaro system — a quieter rear than a resonator-only setup.

What does the muffler-tailpipe configuration mean?

This SSMKHN0147 runs a chambered rear muffler feeding the tailpipe, the more subdued rear arrangement on the dual Monaro platform. A chambered muffler reflects and absorbs pressure pulses through internal baffles, so the note stays controlled at cruise rather than open. It's the pick when you want the dual-exit look and flow with a calmer tail than a straight-through gives.

Why dual 2.5in for the Monaro?

The system splits into two 2.5in banks down the rear, which suits the Monaro coupe's twin-exit layout. Twin 2.5in keeps gas speed up on each side while carrying what a V8 produces. We quote only the 2.5in diameter MPI lists for this part and make no claim about combined pipe area.

Will it fit my VX or VY Monaro?

The SSMKHN0147 is listed to fit the Holden VX-VY V8 Monaro. The two-door rear and dual routing are model-specific, so confirm your exact build and rear-end layout with the workshop before ordering so the hangers and tailpipe exits are right.

Oak Flats Muffler Men supplies and fits this MPI dual section in-house in the Illawarra. We measure both banks' flanges, hangers and tailpipe clearance against your Monaro before booking the bay. It's commonly a special order — send your build and we'll confirm availability and timing.
