forget all the sounds etc, all that is irrelaevant at this stage.
pressuming u have a FMIC and boost controller, get your hands on a ECU (if u dont have one) and get it tuned, only then you will take advantage of the hiflows potential
you dont have a S2 unfortunatly, its a S1/.5
S2 are 96-98 models S1 are 93-95
also i think that front bar is a jun style, wheels i think impul and a kakimoto exhaust
i got my bits from earls, pirtek and JJ
got the 34 row from JJ and went and got the billet filter relocator from earls and went to pirtek and got some custom braided lines with fittings for about $150.
i had leaks with the trust sandwich plate, the earls billet fitting has screw in fittings.
