Ford FG V8 Sedan 2.5in L & R CatBack Hotdog/Muffler (SKU: SSMKFD0187) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive SSMKFD0187 is a 2.5in left-and-right cat-back for the Ford FG V8 sedan, pairing a hotdog resonator with a muffler. The hotdog-then-muffler combination at 2.5in is what defines it: a free-flowing resonator working alongside a chambered muffler, rather than two full mufflers.
A hotdog is a compact straight-through resonator that flows freely while doing light tuning of the note; the muffler behind it is the chambered unit that controls volume. Combining the two — instead of running twin mufflers — leans the system a touch freer through the resonator stage while still keeping a silencer in the loop. On the FG V8 sedan that's a middle-ground note between fully subdued and opened-up, and it follows from the layout, not a published figure.
This is a cat-back, replacing the exhaust from behind the catalytic converter to the tailpipes and leaving the cat in place. At a 2.5in bore it's the tighter-pipe option sized for the V8 sedan, and the left-and-right layout splits to dual exits to suit the FG's body. The cat stays where Ford fitted it, so it's the rear-reworked, emissions-hardware-retained path.
The SSMKFD0187 is listed to fit the Ford FG V8 sedan. With several FG series carrying detail changes, confirm your exact build and rear layout with us before ordering so the left-and-right pipework, hotdog and muffler line up cleanly.
