Exhaust Systems for the 2015-23 Ford Mustang S550 (6th generation): axle-back mufflers, full cat-back systems, mid-pipes and muffler deletes in T304 stainless, with polished, black and carbon tip options. Exhaust is the one upgrade you hear every single drive. Everything on this page is confirmed for Mustang S550 fitment.
The 2018 refresh changed the front fascia, hood, headlights and tail lights, so anything that mounts to those areas is sold as 2015-17 or 2018-23. Rockers, decklid, doors and the interior carried over, so skirts, spoilers, steering wheels and trim fit all nine model years. This page covers EcoBoost, GT, GT350, GT500 and Mach 1; use the Model filter on the left to see only parts for your trim.
Materials run T304 stainless steel. Every system is TIG-welded T304 with mandrel-bent tubing and includes hardware.
Frequently asked
Will I get drone at highway speed? Resonated systems here are tuned to stay quiet at cruise and open up under throttle. Non-resonated and muffler-delete options are louder throughout and say so.
Do I need a tune? Axle-back and cat-back systems are bolt-on with no tune required. Header or downpipe changes are the only ones that may need one.
