I have 2017 fitted with the Akrapovic GP style slip on silencer only, the rest of the exhaust system is stock including the cat. Has anyone had this setup noise tested? I am heading to a track day at Spa next month where the stated limit is 100dB static (at what revs is not specified!) and I wonder if I will pass. If anyone has relevant experience I'd be grateful if you could let me know. Thanks.
