Hi there a mate of mine gave me a GFB stealth FX BOV as an early xmas pressie and i want to put on my car I own a R33 series 2 as I want the so called wankfactor sound hehe (personal preference I guess). They vent both to the atmo and plumback. I only have a 3 inch turbo back exhaust, are these good and stop those normal associated problems skylines have with BOV's. According to the GFB website this one is good. But I dont trust em I trust you guys and your opinions. thanks and sorry for the BOV question i wont ask another one this is it.
