is there another bov that uses the same flange as the the greedy. I have a corksport fmic but have been having issues with the type rs bov. It makes some sort of buzzing sound when the car is at or close to 0 boost/vac.
Greddy flanges are for Greddy bovs, and the type rs is pretty much one of the only ones.
You may be able to find a greddy-hks adapter or something like that though.
