My wife’s 2021 Explorer ST. This is a before and after video when I installed the MBRP muffler delete kit. Part # S5203AL. Not too loud or crazy with little to no drone while driving. Gives the explorer that extra grunt that it deserves. Will post another video of the outside while driving. Truck currently has a 93R tune from 5star tuning and drop in K&N filter.
