The installation is not completely finished as there is some belt-slip happening over 5500RPM so I cannot enjoy full power yet - we'll sort this out once my mechanic returns from his summer holidays. As far as I can tell the exhaust-note is unchanged but since there is more flow I think it's louder at WOT. I'm very happy to have a valvetronic-type exhaust so I can choose whether to be noisy or not...
