Explorer ST Exhaust Comparison

[T5ewell]

I’m wondering if I did a 3” x pipe or 3” H pipe with a muffler delete, if I’d get the sound volume I’m looking for but cancel out the drone. Not sure how it would play out in actuality

I want a little extra sound but no drone.

I'm considering replacing the midpipe/resonator with an "H" or "X" and leaving everything else.

Does anyone have experience with a setup like that?

MRT offers that, it is a resonator delete H-pipe: https://www.shopmrt.com/2020-Ford-Explorer-ST-MRT-Sport-Touring-H-Pipe-p/90r227.htm

I'm really interested in trying out the Valvetronic universal valved muffler.
https://valvetronic.com/products/universal-valved-exhaust-kit

There is a youtube video of it being installed and got me excited because it can be loud and fun when open or hopefully almost stock volume when closed when hauling the family around.

I need to get over to an exhaust shop and see how much it would be to install this. I do worry there will be drone or it could sound raspy since it is a universal muffler so my thought to attempt to fix that would be to add the Magnaflow Tru-X Resonator. https://g8only.com/product/magnaflow-tru-x-enclosed-x-pipe-muffler/

This would all be trial and error so it may be a while before I would do this since my wife will kill me for spending so much time and money on something with no guarantees.

A quality resonator will do wonders to eliminate drone and rasp.

If your wanting to do a Valvetronic setup, maybe wait... they MAYBE coming out with a exhaust just for the ST. I know they're building a ST right now as a caution car.

Should I look for a resonator designed for an st or any 3” resonator would do? If I wanted to go 3”

Perhaps some more research is in order before you start tossing terms like resonator around! The reason I say this is it's application specific and has nothing to do with 3" or 4" or 2"...

I understand that, to my understanding the resonator is more about tone and pitch where as a muffler is for volume. Also resonators eliminate drone. Please correct me if I’m wrong.
My question was if I’m looking for a resonator, does it have to be one designed “for an ST” or can I just buy one from a reputable shop. If so, how do I know what would be best for an explorer

Here's a post from @UNBROKEN- a member of this site who is far more knowledgeable than I on the subject:
