Flow question crush vs mandrel
i can get a crush bent exhaust done for dirt cheap from a local shop but they do crush bent. so my question is how much of a flow difference is there between the two? ive got slp headers and the downpipe i have is 3" from there i will have them do 3" back to the "Y" and then dual 2.5". so really the only crush bends will be after the "Y" split. id think the crush bends that far back shouldnt cause too much of a problem as by then the exhaust gas should have had enough time to cool. input needed.

Probably wouldnt matter much that far back, but you might make a few more ponies mandrel bent. Try to get them to order a few mandrel bends and work with those, thats what i did. Otherwise, just make sure it doesnt look too ghetto. It will be fine.
