I was fumbling around the yoobtoobs like I usually do when bored - and came across some videos about active exhaust deletes (had considered this with my 2016 Scat Pack) and eventually came to a video about 2019+ models not throwing check engine codes if you just remove the (springs?) from the AE valves - the piece that moves the valve open and closed (pops off)

Not sure if anyone has confirmed it works on 2020s / 2021s but I went ahead and gave it a go on my 2020 and haven't had any issues.

I used some solid gauge electrical wire to tie the valves open (there's a hole you can feed wire through) and I wrapped the end around the closest threaded post so it's held nice and snug by the bolts that hold the assembly up.

Have you noticed if the sound seems louder all the time? I have mid muffler delete and it sounds real good but wondering if it would sound a tad louder with this free mod.

Just did it. So far no CEL. Might have to put 50 miles on it to double check. Heard some throw codes after a period of time. Hope thats not mine.

Ive had mine done for a bit now, no codes
And sorry I didn’t get back to you sooner on the gauge - it was probably 16-18 gauge but solid and not stranded

interesting. hopefully they just coded those stupid things out. I battled with my 2015 after changing the exhaust and then had a couple of the motors die, check engine light on a bunch of times. i could never understand why they would throw a CEL
