I want to replace the stock exhaust with something with a little more sound. Can someone describe the difference I see in the different options I have read about; x-pipe, h-pipe, straight.... Will a slip on exhaust give me a much deeper sound or do I need to replace the headers as well? I've seen videos of bikes with the cat removed and using the stock muffler is sounded nice but not sure how involved removing the cat is. for those that have removed it, is it difficult? Any suggestions? I have used Hindle on my sleds and was happy with it. How are their exhausts for the bikes?
