Sized at 3in across a dual layout, the MPI Automotive SSMBM340MF is a centre muffler listed to fit the RAM 1500 and TRX V8 Hemi (5.7L). The 3in bore is matched to the big Hemi V8, sitting mid-system as a chambered centre silencer rather than a rear muffler.
Why a 3in dual centre muffler on a Hemi?
The 3in bore is matched to the 5.7L Hemi V8 — a large engine that wants a freer mid-system path than a smaller motor. Run across a dual layout, this centre muffler quietens by chambering and absorption at the middle of the system, which is where a centre silencer sets the baseline note before the rear section. It's a mid-pipe component for the RAM rather than a complete exhaust.
Where does a centre muffler sit in the system?
A centre muffler is mounted in the middle of the exhaust run, between the front pipework and the rear section. Replacing or upgrading it changes the mid-system silencing without touching the rear mufflers or tips — a targeted way to adjust flow and note on a dual-pipe V8 like the Hemi RAM. It pairs with the rest of the factory or aftermarket system around it.
Will it suit my RAM?
It's listed to fit the RAM 1500 and TRX with the 5.7L Hemi V8. RAM models vary in build, so send your exact spec to the workshop and we'll confirm the centre-section routing and hanger points before ordering. We treat the listing as a guide and check the vehicle on the hoist first.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men supplies and fits this MPI Automotive centre muffler in-house across the Illawarra. We mount the truck on the hoist, fit the 3in muffler into the dual centre section against the factory hangers, and check clearance before sign-off. The SSMBM340MF is held at its listed RRP as a special-order item; we'll confirm availability when you book.
Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
