Plus, I still have to put in the BMC filter.

 

I have a Yosh on my CBR and it screams every bit as much as the Leo Vince that is on my 636! Obnoxious loud sometimes! The Leo Vince is better build quality by far though!

Here is some video as shot at the track that may give you a little bit of an idea.......

i personally love the akra haha

 

I like the sound of my Yosh Carbon TRS. It's a little quieter with a deeper bass tone.
