Why do more exhaust fumes exit the right side?

Can anyone tell me why I can see the fumes exiting the right can (horizontal pipe side) of my Remus half system, but not the left (vertical pipe side)? I thought it may have had a little to do with the exhaust leaks I was experiencing after the installation. I've since sealed the leaks. After firing it up today (in cold weather where you can easily see the fumes) to check for leaks, it still was only noticeable coming from the right side for a couple minutes. I checked the joints where I sealed them with some Permatex copper RTV gasket maker, and the leaks were gone. Sorry if this is a dumb question, but I don't remember my stock exhaust doing the same... or maybe I just never noticed it?

I imagine it's because the right side pipe is for the front cylinder, which has a straighter run than the rear cylinder pipe that has a 90 degree bend and a 180 degree bend in it - I know there is a link between them but predominantly the gas flows in a straight line so the right pipe has less restrictions. I think it balances out at higher RPM though. :)
