Sulphur Smell Need Help IDing

[Paulaner]

Recently finished refreshing my entire rear end, but an having a tough time now identifying an intense sulphur smell that is now present. Thought it might have been diff fluid leaking onto the hot exhaust but its all clean as a whistle with no signs is the diff leaking. Diff was refreshed with all new gaskets and seals. Any other thoughts...exhaust leak maybe???
It only seems to come on after about 15 to 20 or so mins of driving. Took it out for 2+ hours yesterday, no issues at all except for the smell.

Exhaust heat affecting newly painted parts?

Oil and grease on the exhaust pipes burning off?

Possibly, I did paint the diff, subframe and exhaust with high temp paints

Subframe and diff wouldn’t cause that. Exhaust paint is pretty stout too so I would not think it would be the cause either.

Could be cooking off something in the exhaust paint. Weird that it is a sulfur smell though... Maybe the Devil is following him around!!

I'm thinking it's an exhaust leak as I do have a band clamp holding two section of my exhaust together between the rez and the muffler. Previously had to cut it for another project months ago

Seems unusual for exhaust to smell of sulphur though

Hmm...anyone else have thought on this putrid smell

I have heard an overcharged battery can cause this smell. Never heard of it in a Coupe, but apparently a faulty voltage regulator can affect the battery enough to produce sulphur smell. Not saying this is your issue, just something that has been recorded. Good luck and let us know.

Interesting, I'll check battery health and smell once I let it run for a bit. Thanks for the lead
