FORD MUSTANG V8 3in DUAL REAR MUFFLERS WITH SINGLE 4in TIPS for selected vehicle applications.
Category: Mufflers and resonators


The MPI Automotive MBM637MF is a dual rear muffler set for the Ford Mustang V8, finished with single 4in tips. The big 4in tips are the visible signature — a bold exit to match the Mustang's rear, fed by a 3in dual system.
The MBM637MF finishes each side with a single 4in tip, so the Mustang's rear shows a large, dressed exit rather than a small pipe. Behind them sit dual rear mufflers at a 3in bore — the last silencers in the system, shaping the V8's note before it leaves. The 4in tip is the headline finish here, sized to fill the Mustang's rear apertures.
As the rear silencers, this pair sets the note you hear behind the car and carries the visible tips. The dual layout keeps each side of the V8 flowing to its own 4in exit. MPI Automotive lists this as the rear mufflers with tips; the pipe ahead is matched at fitting, and material isn't published by the supplier.
It's listed to fit the Ford Mustang V8. Confirm your exact build with the workshop before ordering, since rear-bar cut-outs and tip positions need to line up for the 4in tips to sit square. Mustang variants differ at the back, so we check fitment to yours.
Oak Flats Muffler Men fits Mustang rear mufflers in-house across the Illawarra. We align both bodies, set the 4in tips square in the rear bar and check clearance, then road-test the note.
