Sulfur smell coming from engine.

Relevance is irrelevant
I've heard stories where people played pranks on people by putting stuff in certain places under the hood. I forget where exactly but I remember they said there are some places where rank stuff can go in, but is a real beatch to get back out.

I have the high flow racing cat that I put on in sept. But its been suspect lately because I get a rattle when I slow down (in lower gears). Rattle is much louder after a good highway drive.
It looked to me like that racing cat is pretty durable. Could it be going already!
My exhaust hasn't felt as strong in the past week or two either.

ROTTEN EGG SMELL FROM CATALYTIC CONVERTER
The sulphur smell from the exhaust, is actually caused by running the engine/cat convertor slightly lean for long periods and then running under a rich condition (ie going up a hill under heavy load) This is when the sulphur smell (rotten egg) is produced.
Under relatively lean conditions, the sulphur found in gasoline is converted to sulphur trioxide, then during the rich running condition the sulfur trioxide is converted into hydrogen sulphide (rotten egg smell) within the catalytic converter.
