Rotten exhaust smell

Hi guys

Soo I've started noticing a smell from my exhaust, and its very much a rotten smell. Seems to have sprung up in the last couple of months (being winter). Have tried different fuels - Ultimate, Vortex and now VPower all seem to give the same smelly result regardless if I'm driving hard or like miss daisy. Starting to be somewhat of a concern.

All research so far seems to point at a Cat going bad or exhaust manifold leak...?

Just wondering if anyone has any thoughts on what my next plan of attack should be.

Cheers
Ash
