Yoshimura Quiet Insert

I did not fit. Thrown in the back of the tool box.

Quiet insert

I bought the full system Rs-4 for my ktm 350. Out of the box I thought the system was a little to loud and rasppy for woods racing. I bought the quiet insert and was a perfect match of throaty and tone for what I was looking for.
