Mustang FN 5.0L V8 2018-23 3in Full System Centre Hotdogs & Rear Bi-modal Muffler 4in Quad Tip.
Category: Mufflers and resonators


The MPI Automotive SSMKFD0318 is a full 3in system for the FN Mustang 5.0L V8 (2018) built around a rear bi-modal muffler — a valved unit that switches between quiet and loud — finished with 4in quad tips. The valve is its headline feature.
A bi-modal muffler carries a valve that switches the rear section between a quiet path and an open one, so the SSMKFD0318 can sit subdued for cruising and open up when you want the FN Mustang's 5.0L V8 heard. That switchable character is the whole point of this build — the valve does what a fixed muffler can't, giving two notes from one system.
This is a complete 3in run, not just a cat-back, with centre hotdogs ahead of the rear bi-modal muffler. The hotdogs are compact straight-through resonators that smooth the note mid-system, while the 4in quad tips finish the look. The 3in bore is sized to the V8.
It's listed to fit the Ford Mustang FN 5.0L V8 (2018). Confirm your exact build and that the bi-modal wiring and tips suit your car with us before ordering, as valved systems have extra connections to verify.
