I have similar filters to yours, but also modified some air horns to fit
inside.
I picked up some 3" aluminum airhorns on ebay, and cut the flare of the horn
off.
I then ground the aluminum flange with a dremel(the mounting face) to create
a flare.
Bolted it up backwards and voila, 3/4" stub stacks.
Although I have not tried the K&N's w/o the stub stacks,
I had to change needles as it was running lean on the top end.
There was no throttle response past 3500 rpm unless I was heavy footed.
I assume that it was getting more air than the stock setup.
