2" DCI ?

Bought 1.75 silicone inlets and DCIs for my N54
Recently upgraded turbos w/ 2" inlets, so now have 2" silicone inlets.
DOes anyone make 2" DCI's ???

I'd hate to bottle neck down to 1.75 for the filters.
Surely this cant be an uncommon issue.

Suggestions?

makes sense!!
Have NO idea what I didnt think to look there.

Just doesnt make sense to me for places to sell upgraded turbos and inlet pipes yet not DCIs too.
Oh well. More money for chinese ebay vendors

Found 2.5" and about every other size known to mankind, but not 2" inlet.
I would possible bit on a pair of 2.5" and try to gimmy rig an adapter down to 2", but everyone knows that the N54 has VERY VERY little room to work with regarding the filters, so dont know how practical that option would be.

You can easily fab up a reducer or possibly buy an exhaust reducer for 2.5" down to 2".
Check your local autozone or whatever you may have near by.
