I have the drag kit, well part of it, and I was wondering from those who have it on a b18b what do the parts consist of. I was thinking a 90 deg elbow with some slim filter of the dome filters like greddy or hks? help please.......also wondering what you guys think of 2 1/2" ic piping.

 

i wouldn't mess with elbow bends. that'll slow your flow. go with madrel bent piping and 2 1/2 is good for the i/c. good luck
