Dual exhaust question

[hmkk]

I've got an Evo 3 catback exhaust and started to notice that only one side (passenger side) seems to have most of the exhaust (white smoke) come out versus the driver side with little to none though both sides feel to have pressure coming out. Also I noticed that the passenger side becomes more hot than the driver side. Not sure if this is due to the 4 cylinder boxer engine that leads to only one side or if something else is happening that Im not aware of.

Please, any input is appreciated. Thanks!

Has to do with the pipe split and where the flow goes when you give it gas. This isn't something to worry about. It's because the pipe is split in two and favors one side. Nothing to worry about really. If you want it to go out of both, you'll need a crossflow muffler or a finer split on the pipe to the axleback section.
