hi guys!
i want to buy a cat back exhaust for my evo6 but i can't find any real data or tests for any of them that i'm interested in

i want to get one between the apexi N1 , the apexi hayabusa and the hks super drager2. which one do you recomend? any other sugestions?

i have found fome dyno data for the apexi exhausts in evo vii but nothing for the hks and especialy nothing (dyno data) for evo 6.....
BTW the apexi have released a exhaust system for the evo vii that is VERY impresive!! the R-95 if i recall correct....

thanx all in advance for your help!
