Loss of power?

Ok some of you may know i got stuck in water week ago, up to the doors with probly half the engine submerged, ended up bending an exhaust flange so it was leaking.

Exhausts fixed and now ive noticed a loss in power since the water incident. It feels alot less peaky and smoother in power delivery.

Im thinking the flange gaskets are blocking exhaust flow a bit, hence the smoother, less peaky power.. the car did have less power after the water, though it was hard to tell as the exhaust pretty loud.


Anyway is there anything else that could have gotten wet that would cause this?

 

oh right its a 04 3.4l V6....
