I liked what Drift had to say about the Thermal exhaust.I've heard lots of good things about those exhausts and the "Stealth" one would be perfect for the street so you don't attract any negative attention from cops.These ehaust are also stainless which(if it's applicable to you,I don't know where you live)will last longer in bad conditions such as all the salt in winter,something I know th Apexi and the Greddy won't hold up to as long(they're only aluminized mild steel).It might be worth checcing into even price wise they're may be a significant difference.
