So I have seen suggested:
SCT's X4 for tuning ($419., 30 min install)
Whipple Mega Cooler ($1095., 3.5hr install)
MBRP Pro Series Cat-Back Exhaust ($1300., 2 hr install)
Sway bar ($270., 1hr install)
Front struts ($205.,4hr install)
Rear shocks $180., 4hr install)
Lowering springs ($340., 2.5hrs install)...all from Steeda (they only have the color blue I believe?)
UPR Catch Can (
2020-22 Explorer ST Ecoboost 3.0 Dual Valve Oil Catch Can Plug N Play with ECSS)
There seems to be a ton of options for tuning and exhaust but I have yet to see a comparison?
