Can the drag gen 3 kit be purchased without the spearco intercooler and replaced with the xs engineering intercooler? Would this be a direct replacement? Is it worth it? I have a cwest front bumper on my 99si would I have to cut it up to fit either of these intercoolers behind it?

 

I'd do it, but measure how much room you need to see if it will fit.

 

Piping might not line up but you can get it modified pretty easy.
