I saw an older model on here the other day that had the pipe come out the other side so that all the clutter was on the same side. I don't know if the same thing could be done to our y2ks or not. I think it might look better, but I don't know how the left side would look. It would be interesting to see.
The only way to get a left exit would be the TBR full system with high left mount. They are very hard to come by, but one was on eBay 2 weeks ago that was brand new...$740 final price.
