Overview

This Milltek Sport cat-back exhaust fits the 2015-2017 Ford Mustang EcoBoost fastback (S550) with the 2.3 liter turbo four. Milltek's systems give the four-cylinder Mustang a fuller, deeper voice than the factory exhaust, with dual or quad outlets. It swaps the factory exhaust from the catalytic converters back, using 70 mm (2.76 in) T304L stainless steel pipework, and bolts to the factory mounting points.

How to Choose

Start with the Sound. Non-Resonated (Louder) drops the resonator for a louder, rawer note. Resonated (Quieter) keeps a resonator for a deeper tone with less drone when cruising.

Then pick an Exhaust Tip Finish: Polished Twin (bright polished stainless), Cerakote Black Twin (a black Cerakote ceramic coating), Brushed Titanium Twin (a brushed titanium finish), Burnt Titanium Twin (a heat-blued burnt titanium finish), Polished Quad (bright polished stainless), Cerakote Black Quad (a black Cerakote ceramic coating), Brushed Titanium Quad (a brushed titanium finish). The finish changes the look only, not the sound.

Planning more power? Milltek also makes downpipes for the Mustang EcoBoost S550.

Fitment Notes

  • Fits the 2015-2017 Mustang EcoBoost fastback. The 2018-2023 facelift has a different rear valance; please call us to confirm before ordering for it.
  • Not for the convertible.
  • Twin systems use one 100mm GT tip per side. Quad systems use two 90mm GT tips per side and need a quad-outlet rear valance, such as the Roush rear valance, on cars built with twin outlets.
