I was wondering if anyone has ever shortened there stock muffler, and if they did what were the results. I have a 2007 and thought about shortening it from 15" to 10". I don't know how it will effect the power band, ect. If it does not work I can always pick up another one on ebay. I was thinking it may help a little with weight distribution if it doesn't hurt the power band. Also wondering what some of the lengths of after market mufflers are?
