Do I have an exhaust leak?

[mfergel]

Came out to the truck running in really cold weather and noticed this. Is this an exhaust leak or is there some kind of secondary exhaust outlet built into the exhaust system? I should have probably taken a short video instead but there was a good amount of exhaust coming out of this just in front of the rear suspension.

That's the new style resonator they are using.

that new resonator is the welded on patch at the left rear

Possibly. I'd have it checked to be sure, or you could slide under and take a look.

Interesting. I'll have to take a look underneath though I guess. Mine seemed to be coming more from right after the muffler versus way back behind the wheels.

Factory weep hole?

Yes there’s a little hole on the muffler towards the back. That’s probably where it’s coming from. I wouldn’t be too concerned, the whole exhaust is a welded one piece.
