Overview

This Milltek Sport cat-back exhaust fits the 2021-2023 Ford Mustang Mach 1 (S550) with the 5.0 liter Coyote V8. The same active valved systems Milltek makes for the Dark Horse also fit the Mach 1, with a choice of H-pipe or X-pipe crossover. 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 System. H-Pipe (Loudest) uses an H-pipe crossover for a deeper, traditional V8 rumble. X-Pipe uses an X-pipe crossover for a smoother, higher-pitched V8 note.

Then pick an Exhaust Tip Finish: Polished (bright polished stainless), Cerakote Black (a black Cerakote ceramic coating), Brushed Titanium (a brushed titanium finish), Burnt Titanium (a heat-blued burnt titanium finish). The tips measure 115 mm (4.5 in). The finish changes the look only, not the sound.

Features

70 mm (2.76 in) T304L stainless steel pipework
