No real reason..... I like it 
awesome job it looks very good from the picture. I've seen something similar on a different truck before it was the 6637 "stacked" with a spectra filter on a hopped up truck before. I really couldn't think of a real good reason for it.

From an absolute air flow perspective, dual intake filters are not necessary at all, especially when you're starting out with a 6637.
Two positives DO come from this, though:
1) reduced pressure drop for the incoming air -- the air can get to the turbo easier with less restriction, and
2) your filters will take longer to get dirty -- less frequent require cleaning/replacing.
While increasing filter surface area, though, there is a point where the intake tube itself will be the limiting factor due to friction through the tube. That said, I really don't think you could fit enough air filter surface area under the hood to ever see that happen.

well im the buddy lol
we did it to both of our trucks, and i believe i saw more of a difference cause im tuned. i def. felt and saw an increase in spool up, no boost gains, but a definite increase in spool. i also saw lower egts (approximately 70*-100*) throughout the whole rpm range, cruising and accelerating.

I did end up finding that I had a small psi increase with my foot on the floor.
Diehardstroker is have some slip issues so he hasn't seen an increase in psi yet but we did find performance in other places.
I'm still pretty much bone stock @ 19psi. I reached 20 until it leveled off.
