Question Worst Sounding M4 (HELP)

So lets start with whats been done to the car, Valves Pulled (forced open), and Secondary Cat removal with straight pipe, and Resonator Delete with X Pipe (pretty sure it was X pipe). Well I'll let the sound clips speak for themselves I attached one from my perspective in the car reving to around 5k RPMS, and one from me pulling off. Now the car sounds pretty good to me some times I love it windows down and just let it rip. But also im not stupid it does sound like a fart can 9/10 times which now I know I went with the cheapest possible options all around for exhaust, im 20 years old, and dont have 3k for a exhaust system. So with that out the way lets talk about how I plan to fix this, and what I want and whats important
Sound Volume: Very important never really had a loud car that rips down the road, I want that would prefer to be the same or if not significantly louder then my current exhaust.
Drone: I dont see why people hate drone I actually enjoy it a bit if I dont want to hear it i turn my music up halfway and its gone so I could care less.
Overall Sound: I do want it to have more of a deep sound and make it sound less like a tin cam.
Solutions: Right now my main fix for this is to buy a ARM resonated Downpipe
That video i feel is kind of similar to how I expect my car to sound after which im happy with sounds a little deeper, and a little louder.
Midpipe and Downpipe: Or I could swap to the classic equal lentgh setup and a basic vrsf catless dp, or the arm resonated and see what we get, but again this will cost around 1.7k which Id rather not spend right now.
So what are your guys thoughts after hearing my setup is it fine? Is it complete shit? Does it sound good? Let me know your thought and if anyone has a setup similar to mine straight pipe + resonated DP please send videos.

My setup is the streamable links at the bottom So to sum it up would the ARM Resonated downpipe benefit my current exhaust system by making it a little louder and give more tone.

Sounds like just about every UEL F8X w/ a down pipe. If you want a change in tone then you will need to go EL. If you want to reduce rasp you should put your primary cats back on and start adding back resonators until rasp is where you want it.

Probably do the single midpipe, fine someone selling it here. Or hear me out, since you are young, just save up money for the exhaust. You gotta pay to play pimp. Not in a civic anymore where you get cheap parts

Single mid is what you want. Look at mad and vsrf for budget friendly options.

Agree with the single mid-pipe recommendations. I have stock DPs, AA single mid-pipe and AA three-can muffler. It’s loud but not too loud and it’s smooth sounding for a S55.

I have Catless Downpipes, AA Resonated Single Mid, and MPE Muffler. I think it's the best setup.

You can get a similiar setup without the MPE Muffler and it will sound close to as good. If you get resonated downpipes, you can get the VRSF non-resonated mid for wayyy cheaper than it's AA resonated counterpart.

Appreciate my man I’m about to get a resonated down pipe is a ue mid pipe much different then a resonator delete and secondary cat delete? Thought they were the same thing for the most part as it’s just metal pipe

Lots of posts if you search here that Resonator and secondary cat delete on stock exhaust doesn't sound good. A single mid that deletes both but uses a 3.5 inch pipe instead of duals is the way to go. Mad, vsrf or aa depending on your budget are all good choices.
