Anyone try using the full yoshi at Laguan Seca?

I just took mine off and will be using the 300 at Laguna Seca. But the stocker is so ugly.

The full yoshi is pretty loud so i'm not going to bring the bike there and and can't pass the db.

Any suggestions for quiet after market full systems? The area-p doest look that great either but i rather have that than stock.

I thought the yosh was the quietest since it meets california regulations

It most definitely does not meet California regulations, I have it on my bike and it's completely illegal. To the OP I would say put the silencer insert in the muffler and you should be fine noise-wise, at least mine isn't very loud with the insert. Most of the fuel tuner maps for the full yoshi exhaust are made with the insert installed so it shouldn't affect the powerband (I don't think it changes the exhaust flow that much anyways).

The R-77 slip on is EPA/CARB compliant. The full probably isn't.
