Chrysler 300C Hemi 5.7L Sedan, 3in Rear Mufflers for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive SSMBM133MF is a 3in stainless rear-muffler set listed for the Chrysler 300C HEMI 5.7L sedan. At 3in, these are the back-of-the-car silencers sized for a big petrol V8, supplied as the pair that finishes the system under the rear of the body.
The 3in bore is the headline here: it's a larger pipe size suited to a big-displacement engine like the 5.7L HEMI, where keeping the back section open lets the V8 breathe rather than choking it through a stock-diameter silencer. These mufflers sit at the rear, doing the final stage of quietening after the gas has already passed the front of the system.
These are the stainless version of the rear muffler, which is the corrosion-resistant path. Stainless shrugs off the road salt and condensation that eat through mild steel over time, so the back of the system lasts longer on a car you intend to keep. A worthwhile step up on a 300C that already carries a premium driveline.
It's listed to fit the Chrysler 300C HEMI 5.7L sedan as a rear-muffler pair. Because these are the rear silencers rather than a full system, confirm what's already on your car so we match the connecting pipework. Send us the build and we'll confirm.
