Ford FG V8 Sedan 2.5in Dual CatBack Muffler/Muffler (SKU: MKFD0178) Engineered. Quality guaranteed.
Category: Mufflers and resonators


The MPI Automotive MKFD0178 runs twin chambered mufflers down its dual 2.5in cat-back — the more subdued of the FG V8 sedan options, with absorption at both stages rather than a straight-through resonator. It's listed to fit the Ford FG V8 sedan.
Where a resonator targets one frequency, a chambered muffler quietens broadly by reflecting and absorbing sound across the range. The MKFD0178 uses a muffler at both stages of its dual run, so the V8 note is fuller and more controlled than a straight-through layout — the choice when you want the cat-back upgrade without a hard cabin drone.
Cat-back covers the run from the catalytic converter rearward, which is the section this kit replaces. Splitting it into two 2.5in pipes suits the standard Falcon V8 sedan rather than a built engine. The emissions hardware ahead of the cat-back stays exactly as Ford fitted it.
If the sedan does highway kilometres and you'd rather a refined note than the loudest one, the twin-muffler MKFD0178 is the calmer end of the range. It's listed to fit the FG V8 sedan — confirm your build with the workshop first.
