K&N filter source

I'm looking in to getting a set of K&N's for my sprite.  I've got 2 HS2's 
(1.25 ")  If I do go with them I'd like to use a set of ram pipes too.  So... 
what I was wondering is where can I get a pair of K&N's that will fit over 
the ram pipes?  I've seen the setup that VB (or is it Moss) with the built in 
velocity stacks, but it's a little pricey for me, something like $150 I 
think.  


Thanks
