Buddy Club - $500
HKS Hi-Power - $560
Invidia G200 - $580
Tanabe Racing Medallion - $600
Fujitsubo PowerGetter - $590
I like the stock look so i am getting the Invidia G200 (no giant tip, but tip is titanium). Its either that or the Tanabe Ultra Medallion (but its $900, so i didnt list it). Good luck.
