What's causing this???

I use to get some exhaust "spray" from time to time, but lately it has become more pronounced. Could this be from the gas I'm running? And why is it only coming out the driver's side muffler?

It covers the whole area circled.

Oily? Water builds up behind the canflap and when it opens it sprays out. If it is oily it could be turbo seals.

Only if you set it that way. I think. I don't really remember. But that is my bet DME opens it up and water that is in the exhaust gets shot out.

I do....

yeah, I hope that's it....it's just been more pronounced lately

Humidity gets worse in the summer, so condensation water coming from the exhaust, with or without cats, gets worse, too.
