Make every drive sound like a Mustang drive.
The 5.0 V8 is the reason to take the long way home. This 70 mm Milltek gives your S650 GT a more purposeful voice, with active-valved outlets and your choice of X-pipe or H-pipe construction. Four tailpipe finishes let you choose how bold the rear of the car looks too.
SKUs: SSXFD425, SSXFD426, SSXFD427, SSXFD428, SSXFD429, SSXFD430, SSXFD431, SSXFD432
The X-pipe joins the two banks through a crossing section; the H-pipe links them through a balance tube. Both versions here use the same 70 mm diameter and active-valved outlet assemblies. Choose the crossover layout you want, then select polished, black, brushed titanium or burnt titanium tips from the actual combinations below.
Finish your Mustang's rear end the way you want it: polished tips for a bright contrast, black for a subtler look, or titanium for a brushed or blue-toned finish. Choose the X-pipe or H-pipe first, then the matching tip finish. The tip material does not change the crossover layout or turn the stainless system into a full titanium exhaust.

No. These are the S650 GT Fastback systems. The Dark Horse uses separate rear-silencer components and its own system references.
