    Hi
    ive got an Akropovic slip-on end can and was wonder if any of you have either used one or something similar on a trackday, with out a baffle, or know what the db of the can without a baffle is ?
    i'd prefer to go on track with out baffle installed, but not sure if they get shirty about the noise levels, (104db limit)

    I do sound testing at race events in NI. Theres alot of variables can change between two circuits or even the same circuit on different days.
    1000cc bikes arent normally too bad for it and Akra is one of the quieter cans so id say baffle out and 104db should be no problem

    full akky system 103-4 db with baffle out

    100-102 with baffle in.

    more importantly only about a 3bhp reduction with baffle in so why not just leave it in.(if it's already in that is)
