SILVERADO 1500 V8 6.2L 3in LH REAR MUFFLER (SKU: SSMBM730MF) Engineered for selected vehicle applications.
Category: Mufflers and resonators


For a Silverado keeping its standard tailpipe routing, the MPI Automotive SSMBM730MF is the plain left-hand 3in rear muffler for the Chevrolet Silverado 1500 V8 — the offside rear silencer without the stub or twin-tip options bolted on.
This is the base SSMBM730MF: the left-hand rear muffler in stainless, set up for the conventional rear exit. There's no stub for tray or canopy routing and no twin-tip outlet — if your Silverado runs the factory-style offside tailpipe, this is the unit that fits that position without extra pipework to plan.
A rear muffler is the last chambered silencer in the line; this one is the 3in left-hand unit. Inside, baffles reflect and absorb the 6.2L V8's pulses so the note stays controlled at the tailpipe. The 3in sizing matches a free-flowing system rather than a restrictive stock one, quietening the sound without choking the rear of the exhaust.
It's listed to fit the Chevrolet Silverado 1500 6.2L V8 as the left-hand rear muffler — run it with the matching right side for a complete pair. Confirm your variant and any earlier exhaust changes with the workshop, since these trucks vary in setup.
Oak Flats Muffler Men fits these in the Illawarra. For the standard unit it's a direct swap into the offside rear position: we check the hangers, align the body away from the bumper and tray, and clamp it up. Send your build and we'll confirm the part and book the bay.
