I was actually thinking of getting the Akra slip on (seeing as I cannot afford the full system). When you say that the difference is unbelievable, are you referring to sound, performance or both.Originally posted by Naughtyninja
I had the Rs-3 on my 636 before I crashed. It was noticably louder then stock, but the performance was garbage. I now have an akra cf slip on..and the difference is unbelievable.
