alright,hopefully within the next 5 months or so,i will have a new exhaust system on the Z...now im debating between the tanabe and stillen...as both of them seem to be on the "quiet" side so to say,which is what im looing for,if anybody has any input on what they think is better,personal experience etc,i would greatly appreciate it. theres a bunch of info on here for the stillen,but it seems not to many users have the tanabe,again if anyones got any input,thatd be awsome!!
