New exhaust.

I think you should just take it off
I love the massive sounds that engines make without mufflers. Especially those old Chevolet V8's. Beasty.WHen you reved it it just sounded like wind on the mic.

Well, the problem with a straight pipe, is it messes up your intake valves. Unless you have a long straight pipe, then you maintain back pressure and they will last a little longer until cold air hits em'. On a bike, no exhaust would cause a lot of problems especially with a two cylinder four valve engine. Just sayin'.
