Have any of you guys done anything with your blowoff valve(s)? I put a cold air intake in which helped a lot but I really want to do something better. I heard it's possible to just vent right under the hood and it gives it a good sound. Any ideas?

Yes, you can disconnect rubber hose from each blow off valve and plug the end of that hose with 3/4 sprinkling pipe plug.
Or take those hoses completely off and put 7/8 rubber leg foot over the niple in intake pipe - sold in hardware stores to be used over chair legs.

Look up on YouTube , there is some videos " how to vent to atmosphere ecoboost "

It's hard to get to the rear blow off recirculation hose , might need to take whole intake pipe off and blow off to disconnect that darn hose.

Aftermarket intake decreases performance unless you have the type that is fully closed in and is routed to radiator suport - don't think there are any for explorer though.
It was proven by numerous people at the drag strip (on SHO - which is identical in layout and under the hood parts). It's is due to introduction of warmer air, as aftermarket intake takes air from under the hood.

After watching a video online near that video "don't vent to atmosphere" I ordered the part and took off my tire to find out there is no blow off on a 2015. I did what you suggested and it makes such a difference.

You do not have to take off the tire, that video was for 2.0 ecoboost. Sport come with 3.5L. You need to watch correct video - SHO or Explorer.

Seems like it would get pretty annoying over time

Day to day diving I only hear light sound if music is completely off. You need to hit full boost to it loud and clear.
With only front one disconnected, can hardly hear (in car) after hitting full boost.

Agreed. It's there when you want to hear it, but with light music you can barely hear it. Easily reversed if it's annoying.
