Well i made junkyard turbo setup for my del sol. Most of the charge pipes are from dsm. Except the elbow where the stock 1g dsm bov sits its made of metal. The bov is a 1g of a Talon. And well it hardly makes any noise. My friends eclipse automatic is a 2g and his bov is plastic and sound hard. Mine is metal and sounds nothing at all. Im pushing 8lbs of boost and when i rev it the bov just gushes alot of air out but makes no noise?? Well i havent heard any dsm 1g bovs, but i wanted to know if these bov make no noise at all. Could the 2g bov is loud just because they are made out of plastic sound hard??
