exhaust as said above is a jasma catback, only one dent underneath the cannon pretty sure it will hav no effect on flow or make any leaks, front is from FLYN and did set me bak $280 i think only a month or so ago.
as stated R34s hav options such as 3 gauges, GPS/Nav/TV or nothing... this GTT got the luxury GPS one so ther is no gauges other than the ones on dash (oil pressure, fuel and water temp)
