Chrysler 300C 6.4L SRT8 Sedan, 3in Rear Mufflers for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive SSMBM132MF is a stainless 3in rear muffler set listed to fit a 6.4L V8 sedan. As the rear section, it's the final stage that settles the note before the tailpipes — built in 3in to match a big-capacity V8 and in stainless for corrosion life.
A muffler quietens by absorption and reflection, routing gas through chambers and packing that soak up and cancel sound. Sitting at the back of the system, this rear set is the last stage the exhaust passes through before the tailpipes, so it shapes the note the car finally makes. Supplied as rear mufflers, it replaces that rear section rather than the whole exhaust.
The 3in bore is sized to suit a large-capacity V8 like the 6.4L this is listed for — bigger pipe to match the engine's breathing. As a sedan rear section, the routing and exit suit the sedan body. Built in stainless, it resists rust and heat bluing, so it's the corrosion-resistant choice for a rear muffler set that lives under the back of the car.
It's listed to fit a 6.4L V8 sedan. The supplier doesn't publish the make, model, series or years for this listing, so send us your exact vehicle and build and we'll confirm the rear-section fitment, clearances and tailpipe exits before ordering.
Oak Flats Muffler Men fits stainless rear muffler sections like this in-house across the Illawarra. We confirm the set hangs and clears the rear floor, the tailpipes exit evenly and the section ties into the system cleanly. The SSMBM132MF is a special-order item with a published RRP of $1,500.99.
