Sold my 2009 Phoenix today. So yesterday I took off my Hyperflo slip on matched with Arrow Headers and put back on the stock exhaust. You never realize how quiet and restricted the stock exhaust is until you take off your aftermarket one. After the job was done I promise myself every bike I get in the future I will not ride it till I have a full exhaust for it. So anybody debating on spending the money, believe me it's definitely worth it.
Sad thing for me is we have to run stock muffler at our track near Vancouver, Canada. After my engine build this winter, i'm getting a dyno tune with maps for both stock pipe and Hindle full system. It will be interesting to see the differance in power between the two. I suspect there won't be as much differance as people would think. I'll post the results, probably in january.
