problem please help.

Today I chanced stock exhaust muffler back to where I had dual borla mufflers earlier because it made to much noise with borlas... And now it seems that most of smoke is coming from other side. Anyone knows how the stock muffler is supposed to work?

thanks

If I remember correctly, the stock muffler has two inlets and two outlets but Y's to a single tail pipe. I believe the right side of the muffler is a closed port so only exhaust comes out the left side port. Now mind you I'm going off of memmory of what my exhaust guy told me when I had mine done. The exhaust outlet could be the right side and the left is closed. Either way one side is closed if my exhast guy is correct.

yes it must be like that.
