AWE SwitchPath Cat-Back Exhaust for 2024-2026 Ford Mustang Dark Horse

The AWE SwitchPath™ Exhaust for the S650 Mustang Dark Horse is a cat-back built specifically for the S650 platform, not a carried-over S550 kit. It keeps full factory valve functionality, so the Dark Horse's drive modes and programmable buttons still control the valves, quiet when you want it and fully open when you want to be heard.

A precision-engineered H-pipe delivers a rasp-free muscle-car tone, and the clean, non-baffled, straight-through layout is handcrafted from 3-inch U.S.-sourced CNC mandrel-bent .065-inch-wall T304L stainless steel. Slip-fit inlet adapters give a perfect fit to the factory headers while leaving an open 3-inch connection.

The system finishes in quad 5-inch double-walled tips in Chrome Silver or Diamond Black, and at 59 lbs it weighs less than the 66.5 lb factory system. It is engineered, designed and manufactured in-house by AWE in the USA.

Frequently Asked Questions

Do my drive modes still control the valves?
Yes. The SwitchPath™ system retains full factory valve functionality, including drive modes and programmable buttons.

Does it fit a Mustang GT?
This listing is for the Dark Horse Fastback with factory active exhaust. AWE builds separate systems for the S650 Mustang GT.

Is it street legal?
AWE lists this system as 50 State Legal because it does not tamper with any emissions control or monitoring devices; it bolts on behind the catalytic converters. AWE does not publish a CARB Executive Order number for it, and local sound limits vary, so check the rules where you drive.

Do I need a tune?
No. AWE does not require a tune and guarantees no check engine light when installed properly.
