What is the main reason for the sluggish feel?

There is conflicting information online on whether or not the 4rh gen longtubes will fit or not. The ones I was looking at were 4th gen JBA headers BNIB. I was going to make them fit one way or another.

I'm a newbie on working on the truck and limited tools that i did not want to risk it.
I read that configuration and space was the issue. Especially on the driver side.

This guy installed 4th gen OBX headers on his 2019 5th gen

Headers | 5thGenRams Forums Headers

Yeah, I saw that, but I don't think I've seen those LT Headers available.
But if he was able to, then I guess you can do it with any brand.
I did definitely see 4th gen LT and shorties available in market place.
