MPI Automotive Ford FG V8 Sedan 3in Dual Catback Hotdog/Muffler.
Category: Mufflers and resonators


Routed as a straight dual, the MPI Automotive SSMKFD0183 is a 3in cat-back for the Ford Falcon FG V8 sedan built around a hotdog resonator and a chambered muffler. Each bank runs its own mirrored pipe to the rear, and the hotdog keeps that dual path flowing where a second muffler would close it down.
Rather than handed left-and-right pipes, this system mirrors a matched pipe down each bank — a straight dual. With a 3in bore carried both sides and a free-flowing hotdog in the run, the FG V8 keeps the gas moving on its way to the rear. The dual routing is part of the part: both banks are carried evenly, and the chambered muffler at the back trims the final volume so the result stays composed.
A hotdog is a compact straight-through resonator — it lightly tunes the note and cuts drone while flowing freely, then the chambered muffler behind it settles peak volume. So this build sits between fully subdued and wide open, which is the point of choosing the hotdog over a second silencer. The record gives the 3in bore, the V8 sedan fitment and the hotdog-and-muffler layout; no sound or power figures are published.
A cat-back swaps everything behind the catalytic converter — pipes, resonator and muffler — while the cat and front pipework stay as the factory fitted them. So the SSMKFD0183 reworks the rear of the FG without disturbing the emissions hardware ahead of the cat. Confirm road compliance for your build with us.
