I haven't noticed too much of the suction issue... but since these are AN fittings, I can always fit AN hoses on them.... I gotta put it under a dyno to see whether if these things collapse or not....
Personally i have a Stock Exhaust Manifold, so there is a lot of clearance between the hose and the manifold... I would however suggest AN hoses if it was an aftermarket.... Then you won't have any problems....
