Ok....so I just sawed off the main cat and all the resonators....i'm going to a shop 2morrow to get them to throw a straight pipe on there and then some straight flow mufflers...any reccomendations? Only reason i'm doing this is cuz i'm a cheapo and i'm not gunna spend 600 bux on exhaust....(even tho i spent 1200 on it for the S2000) lol. Should i try to get custom 2.5" if they will do it? Anything specific I should know?
