go fast bits gfx stealth bov

Ok guys i know for some this is a like it or hate it subject but im looking for some clarity. I receive my new 2007 impreza 2.5 wrx this week and bought the above mentioned bov and have read that some people say it does harm to your car the fit an aftermarket dump valve. Clearly i do not wish to harm my new car in any way as this is my first subaru and turbo charged car.So is it ok to fit these or not?

They do f all for the car performance wise and they make you sound like a bus, but each to there own

i do realize it wont give me any increase in bhp but some people actually like the sound but as stated its not a I LIKE IT OR I HATE QUESTION its a will this harm my cars performance ? :noway:

theres no real reason it should, in theory it should decrease turbo lag a small bit, but people generally dont notice a difference
