lots of people have the Greddy RS. Its a great bov and doesnt leak. As for the adapters, depending on the hard pipe that you purchase, just choose the option for the Greedy flange

for example:

takea look at that page. ItsAGP's hard pipe and you can opt for the greddy flange.

 

mm wow this looks more complex than the STI, but this Greddy BOV Type RS should it fit with the stock's car BOV Flange? or not?

 

in order to install the BOV, you need to replace the stock pipe.

 

oh man!!! well that means i have to cut that third exhaust that comes under neet the left side?? thats the one that you're talking about??

 

third exhaust?

you've got 2 pipes that is recommended to replace. Hot side pipe (under the car, you'll see a pipe coming off the left side of the intercooler) and the cold side pipe (its the pipe that comes off the right side of the IC and into the throttle body).

if I remember correctly, the Greddy bov gets installed on the cold side.

 

ohh it looks like and third exhaust, the one that i always see under the left side, by the way its louder than the one on the rear.
