Default Why does my car smell like rotten eggs everytime i floor it?

Whenever i go wide open throttle, my cabin smells like a bad perm/rotten eggs. Why is this? it ONLY happens when i do this.

Sounds like a bad catalytic converter usually that’s what rotten egg smell means but wait for other opinions before you go buy one there very expensive.

would a bad cat cause a strong in-cabin smell?

could be true because i swapped out my exhaust last week and this is the only time i've smelled it. I might use a gasket between the cat and axle back pipes..

I had this issue on my M5, it was bad cats. I changed the gaskets and the smell was still there! I removed the cats and replaced it with a straight pipe, smell gone!

If emmisions is an issue, replace your cats.

Just to confirmed, I have my car check out at the dealer and the mechanic told me due to certain brand of gasoline have more sulfur. That will create the foul smell and it's normal under hard acceleration.

The smell you are smelling is hydrogen sulfide (H2S). It results from using fuel with high sulfur content. (Much of the fuel sold in the US contains a LOT of sulfur -- much more than is legal in Europe, for example, though the Govt. has mandated a reduction to Euro sulfur levels in Diesel fuel over the next several years). You can sometimes reduce or eliminate this problem by changing brands. That is often not a permanent cure since refineries usually buy from a variety of suppliers and the amount of sulfur in any one brand varies as a result.

You are absolutely right, our fuel here contains sulfur too. Sulfur is really bad for your injectors, especially on newer cars with DIrect Fuel Injection system!
