MPI Automotive VF Sedan V8 6.0L, 6.2L 3in Dual Rear Mufflers.
Category: Mufflers and resonators


The SSMBM478MF-VF is a 3in dual rear muffler set built for the VF sedan V8 6.0L/6.2L — a matched pair for the sedan's twin rear, sized to the larger-displacement late-model V8.
This is the pair of rear mufflers for a VF-platform V8 sedan running the twin 3in rear layout. Two matched units, one per bank, keep the note and flow even across both tailpipes. The 3in bore suits the 6.0L and 6.2L V8 rather than stepping the system back to a smaller outlet.
On a twin-rear sedan, fitting two matched mufflers keeps back-pressure and sound balanced side to side. A mismatched single can throw the note off between banks, which is why this set is supplied together for the left and right of the system.
The set is built to a 3in bore to match the twin 3in rear of the 6.0L and 6.2L V8. That keeps the larger-displacement engine flowing to the tail rather than pinching it down. Confirm your exact engine and rear layout with the workshop, as feed detail can be thin on this listing.
