[Mr C]

Slighly worried my bike will be too loud for Oultons 105db limit. My S4 has K&N Open airbox & Termi's do you think it will be ok??

No problem at all, I'd be surprised if they even test it.

They tested us at the trackday we did at oulton, at least one bike wasn't allowed out because it failed the noise test, it was loud though!
My 900 monster is fairly noisy, old ish carbon oval Leo Vinces plus open airbox etc, it made it through OK.
If you're worried, take a bit of rubber hose or sheet to make some rubber tube, to fit over the end of the cans and extend out a bit, secured with jubilee clips, this is quite effective in absorbing some of the sound pressure and reducing the dB readings.
