It smells like eggs
Lately when I drive around I've been smelling a nasty rotten egg smell from my car. I'm guessing most likely it's from the exhuast. My last oilchange was like 1200 miles ago.
You guys think something messed up with my cat? I have a stock set up for headers / cat / exhuast... so nothing was ever touched down there...
Also it could be when I polished my exhuast tips with chrome polisher I got some crap in stuck in there.
Should I get this checked out at the dealer? I'm still at 17k miles so I'll guess it's under warranty.
Thanks in advance guys.

Typically you get that egg smell from a new cat or if your cat has gone bad, normally you'd see your temp creep up with some noticeable performance loss (plates will block each other), so I doubt it is the cat. Something else could be at play, but I'd give it a week or two unless you notice any of the symptoms above.

I've noticed a similar smell from my car and there's only 8,000 kms on it. It's only intermittent though. It would smell for like 10 minutes, then go away. I can't pinpoint where exactly it's coming from.

Am I understading this correctly?
But with a new cat, such as the Random Technology cat, you will have an "egg smell" forever or just during break in of the cat?

I don't think it's a dead animal. I've already had that happen and it was $1200 in repair costs for that chewed up wiring harness.

was reading around and found that low amounts of sulfur do exist in our gas (worse in Asia) which can turn into Sulfur Oxide in the catalytic process and could possiblly contribute to some of that eggy smell. My guess is the gas we used has a little more sulfur in it than normal.

Rotten eggs- classic case of an overly rich mixture. Are you getting less mileage than before? Do you have check engine light on? You may want to take it to the dealer.
