I wanted to get a little feedback on. The two brothers exhaust system they are offering for the sp1. They have a high mount system that looks good. I wanted to see if it's a good system to run. Or should I think about another system. It's becoming harder to find a good high mount system for the sp1. I was looking at the blackdragon system for my bike but cost is something that will help make my mind up as well. Here is a link to the exhaust system I been looking at http://www.twobros.com/cgi-bin/shopper?search=action&sku=005-9504&searchstart=0&template=Templates/TBRSearchResult-Simple-Hon-RC51-SP1.html.
