I've noticed a few cars out at the local meets that have had bov's welded to the hotpipe and the cold pipe on SR swaps. I've asked a few of the owners why they choose to install the bov on thier choosen side and have heard a series of different reasons to which I know which is better. Is there a concrete reason to install the bov on the hotpipe vs the coldpipe or vise versus? I've also been told by one shop to do the hotpipe and the other shop to do the cold pipe. Im sure each person/shop has a legit reason, just wanted to know which would yeilds the better benefit...or if it even matters. Im looking for functionality(is that even a word)reasons.
