Which GReddy???

Well, I finally have my GReddy exhaust ordered. Currently its the GReddy Street Performance exhaust, but the shop told me that I can get the EVO for the same price. BUT, I might have to wait a bit lnger for the EVO. What do you guys think? Should I wait for the EVO or get the SP now? If there's a chance to get the EVO now should I get it.
What do you guys know about the two exhausts, as far as sound and performance. Any feedback will be appreciated, as my appointment for the SP is three days from now.

I haven't heard the SP, but I've heard the EVO and it sounds sweet. It also hangs a bit higher so you won't scrape as easily.

Without a doubt wait for the EVO. It gives more HP and sounds/looks nicer. In my opinion it is worth the wait.

So EVO sems like the way to go....but has anybody heard or felt the Street Performance? Also, both the EVO and SP have the same 60mm piping, but the SP has a larger tip (130mm). How can the EVO give more hp?
