MPI Automotive Holden VX VY V8 Monaro 2.5in Dual Catback Muffler/Muffler.
Category: Mufflers and resonators


The MPI Automotive SSMKHN0145 is a dual 2.5in cat-back running a muffler on each bank for the Holden VX-VY V8 Monaro. Twin chambered mufflers are the distinguishing point — it's the most settled-sounding of the dual Monaro builds, with sound control on both sides.
Carrying a chambered muffler on each of the two banks gives the SSMKHN0145 sound control across both exits, the most subdued of the dual Monaro arrangements. Chambered mufflers reflect and absorb pressure through internal baffles, so the V8 note stays measured at idle and cruise. It's the choice when you want the dual-exit flow without an open, harder tail.
Splitting into two 2.5in banks suits the Monaro coupe's twin-exit rear and keeps gas speed up on each side. It's the balanced flow path for a V8 that isn't chasing the single largest pipe. We state only the 2.5in diameter MPI lists — no combined-area figure is published, so none is claimed.
The SSMKHN0145 is listed to fit the Holden VX-VY V8 Monaro. The model's two-door rear and dual routing are specific, so confirm your exact build and rear-end layout with the workshop before ordering so both banks, hangers and exits line up.
Oak Flats Muffler Men supplies and fits this MPI dual section in-house. We check both banks' flanges, hangers and clearance against your Monaro before booking it in. It's usually a special order at this price — send your build and we'll confirm stock and lead time.
