CF bonnet wont pass

The oil catch can... If it is recirculating back into the intake, then its okay. But if it vents to atmo, then no.

97db is well over the legal limit of 90db in WA. But more often then not, they dont actually pull out the electronic thingamajiggy to test it. As long as its not excessive, you should be okay. Consider putting a mid pipe resonator on the exhaust, it will cut noise significantly without any loss of flow.
