Bama why did you put it back to stock ?
The Banks system uses a K&N filter, which lets too much stuff thru. I didn't know that when I bought it 2 years ago. So when I got it, I had to keep, so I used it.
My turbo has a high pitched whine to it and the last time it did that, it wasn't long until I had to put in another turbo.
Power wise, my truck is right where I want it and I just don't want to have to go to turbo #4 anytime soon, so I thought it was best to just go back to the stock system, which breathes just fine.
I have found an AFE replacement filter that fits in the stock canister location. It comes in its own canister and is reusable. So I may look into using that later on.
