Obp or equivilant suitable for impreza breather system. I gather RCM make a good one too?

Need one fitted at current tune especially as I love a good 1/4 mile launch!

 

I,ve got one which I bought off Tyron (Cannon Fodder) but I,ve got different plans now and have decided not to use. If you look at Tyrons post on breaking 500bhp spec C in Members Breaking cars, there is a description and photos. It comes with the pipes as seen. It was for my Blobeye . Steve.
