which is a better BOV Greddy type R or RS
 

I am going single and wondering which BOV is the better of the 2. The type R or RS..

The RS look to have a larger valve. Which is better for a street car make 400 RWHP driver.... I like the BOV sounds ....thanks guys...sunil

I think that the Tial and Turbosmart are the best bov on the market, but if I was going Greddy I would choose the Type R bov, just my two cents....
