General LSX Automobile Discussion - Cool air from one side of exhaust?

Is this normal? I noticed it the other day. The pass side exhaust air coming out is not hot at all, even at operating temps. The drivers side is exactly how I would expect it to be.

The car has been sluggish lately and I'm trying to narrow it down a little bit.

Normal LS1 exhaust setup with LT's.

Maybe a deteriorated baffle has wedged itself in front of the outlet that is cool, thus increasing back pressure.

maybe try disconnecting the muffler and see if it makes a diff.

Thanks guys. removing the muffler is a good idea. that will give me a place to start.

It makes sense to me that there is a blockage somewhere since that hot air has to go somewhere. If its not coming out of the exhaust, its going to lead to a lot of backpressure. The headers are as hot as they should be.
