stay away from the fags. lol i just thot that something like this thats so simple for you and causes so much debate everywhere else could have used a proper answer and after reading your reply i now think catch cans are the devil thats the one thing i think this site lacks is alot of tech threads just explaining frequently asked questions. the knowledge you have on engines is awesome tho. the tech section should be yours maybe if you put a catch can between your mouth and your fag it will help keep your breathing system healthy ?
