Steeda Mustang GT V8 3" Catback System
Steeda’s 3-inch/76.2 mm catback uses 304 stainless steel for a deep V8 tone and flow suited to mild or forced-induction builds. Four-inch/101.6 mm polished outlets carry Sidewinder branding.
Includes reducers for the original post-catalyst connection. Compatible with most long-tube headers subject to connection fitment. Estimated installation is 2–3 hours with ordinary hand tools.
Designed to minimise drone, although very low automatic-transmission cruising RPM can increase resonance. Sport mode may help. Not for convertibles or active-exhaust S650 cars.
