Sorry for not getting to you sooner. I think it will. The CAT I had is the same for an '05 Elise. I've been comparing to one of the systems Inokinetic has, the sonic fury, the mounting brackets and pipe routing looks right. Let me do a little more research before we do a deal, if your'e still interested, I don't want you to get pissed if its incorrect. I'll get back to you.
