ok im looking through all these exhausts...and i kinda want one becuz well my stock one is ugly and i like the sound of a good exhaust...but ....some say VTEC and some say Si and some do'nt say anything just 92-96 .....is there a difference? kinda confuses me..i wanna get Tanabe Super Racing Medalion on my Si....for now becuz end of the summer im getting h22a so ...will the exhaust fit on my Si and trasfer over to the h22a with no problems?
