well im looking for a slip on for my bike i thought that i had a shark bought last friday but i got a call from them and there now out and will not have any for a few weeks so...basically im not sure if i want to stick with the shark or go with a ixil or devil now this is not a track bike just a street bike and im looking for it to be LOUD, look good and maybe shave a little weight i hear the shark is the loudest and does look awesome but is VERY EXPENSIVE... the ixil is crazy looking and i kinda like that but im not sure about the weight and i hear they rust... i like the devil because i havent seen it on any bikes really and its not talked about very often it sounds good on line but i know its hard to judge it like that so if anyone has it or has any more info on it please let me know because thats kinda the way im leaning right now.... other then that just let me know what you all think!
