I have heard this also. I was looking at a yosh, m4 or a scorpion and my mananic said he was prettty sure you have cut the stock exhaust for a slip on.JoeyB said:That looks awesome, is that a full system?
I'm looking at getting a slip on either an M4 or a Yosh. I talked to a dealer today and they told me you don't need to cut the stock exhaust for the 04-05 Yosh slip on. Does anyone know if that is true? I told them everything I saw on-line indicated for the slip on you had to cut, both Yosh and M4.
