I know this topic has already been brought up but what is the best full exhaust system for the '04 r6. I've read a lot of what hammy has said and also a lot of what wolf has said and both these guys seem super qualified to help me out here so if you could i'd be extremely appreciative. By the way i love the wolf undertail look but is it really worth 1500 for a slip on? Is there any performance gain there at all? I'm new to this so any feedback would be awsome. Thanks
