    I pick up my track bike this week I've fitted new cans to it so I'm not sure what db the bike is now putting out.Now this is a problem for booking trackdays so does anyone on here know where I could get it tested local to hastings area? :)

    If u got an iPhone download decibel ultra.
    Believe the test is 0.5m at a 45 deg angle.
    Decibel ultra works upto 100 db, or 120 db if u attach an external mic

    /edit and I think it's @ 7000 rpm if 600cc - 750 and 4cyl
    Upwards of 750cc and 4cyl it 5500rpm

    With similar cans on it read 103db @ cadwell and 105 db @ Rockingham? can't work that out think different td providers test differently? it has the baffles in and the last test was done @ 5000 rpm as its a v-twin 1000 spoke to MSV they said if you find a local MSV event u can get your bikes tested for FREE so think I'll just pop down to brands as there's a td soon but either way I think brands gp isn't an option :(

    Wow 2 db at that level is massive. U will get incorrect readings if done in an enclosed space. If you can get down to Brands that's your best bet.

    Don't think my bike is going to pass at brands with the cans I've got on it so brought standard cans off eBay for £45 so atleast I can do the brands gp still going to get my bike tested tho at MSV event tho :)
