I'm close to buying this exhaust, BUT

Definitely a nice looking exhaust. Were you able to find any customer reviews on Nojima? I'm unfamiliar with them and personally, would want to know more about the quality of the product before spending that much and having it shipped all the way from Japan. I, too, am a firm believer in needing to adjust your air:fuel ratio when making a big change to your exhaust system. And, of course, changing out the complete exhaust is a big change. Will your bike run "OK"? Maybe. But I assume what you really want is for it to run as good or better than in its stock form. Otherwise, don't make the change. My .02 is that you should never make modifications that sacrifice performance for style. At worst, your modifications should be neutral in their effect on your bike's performance. Wow, that sounds very opinionated. I suppose I'll leave it in there since you do seem to be asking for opinions. Along those lines, I say if you're satisfied that you're getting a good product, at a fair price, and it gives you the look you're going for, get the bike dyno tuned or do it yourself with a PC-V or have the ECU flashed. Why not take advantage of the added performance you can get from a properly tuned exhaust system? I know, cost. But if you're willing to spend that much on an aftermarket exhaust, I'm thinking you should be willing to spend a fraction of that to get your bike running at its best.

Good luck and let us know if you pull the trigger and, obviously, once you do, pictures are mandatory!
