If you want a really nice quiet exhaust i would recommend the Apexi World Sport. It sounds almost like stock but you get more performance. The only two drawbacks are it is chambered which some ppl don't like (but i personally do, looks more like a stock exhaust) and that it is not completely stainless steel so if you live in a place with a lot of snow or rain, it will eventually rust, but then again all exhausts rust eventually its just a matter of time. You can find it for around $400 on the internet, i think i got mine for like around that shipped for my 98 GS, but i have since gotten a new Teg so i no longer have mine.

Good luck with your GS-R and welcome to HAN!!!!
