    Anyone know?

    Debating whether to run the R77 on the bike on track, or put the standard system back on...

    Limit is 102db.

    I What track?

    I ran my Yoshi R77 at cadwell with NO baffle and it was 104db on the Sunday and 102DB on the Monday. So with the baffle if you are using it should run lower than that.

    It was a 105db weekender

    At Pembrey... it's a weekender.

    I don't want to use the baffle as I don't have a map for it ... I do however have one for the standard exhaust :)

    I have mine set up with no baffles but is fine with it in.

    AS for Pembery You should have no issues as they are very relaxed about TD's and noise. Last one I did there they did no test noise or worry about it. And had much louder bikes on track so you will be fine with it
