Alright, I know there has been about 23094029384 posts regaurding exhausts, and how they sound, and perform... Does anyone have any dyno numbers for any of the major cat backs For GSRs? HKS, RSR, Greddy, Tannabe, DC, Mugen Twin Loop, etc etc. Comments on sound are also quite welcome.

Also, would it be possible/worth it to get an ITR muffler, and get custom 2.5 inch press bent piping from the cat back? Would there be any significant power gains?

You may be asking yourself, why would this DSM owner be asking such questions about GSRs. Well, I will tell you why, I may be trading the eclipse for a nice `98 GSR.
