Weird exhaust sound?

[MikeLYR27]

I did a track day in my 182 yesterday at cadwell park and noticed on the way home the exhaust was making a loud whistle type sound. It sounds like a standard 182 noise but only much louder? Belts are fine, oil is fine and no loss in power. Sounds like its coming from the front of it as well?! I dont think its engine related.

If anyone could shed any light on this that would be great.

Cheers guys

I guess it's blowing from the manifold cat joint.
