Sulfur/rotten egg smell after mashing on the gas

When I go wot and come to a stoplight or where I have to sit for a few seconds, I get a rotten egg smell in the car, most likely coming through the vents. I also smell it outside the car when I get out, until it blows away with the wind.

Would it be a bad cat converter? North Dakota doesn't have emissions inspections so its no big deal, just curious.
 


Alright. Since North Dakota doesn't care about emissions, do you know if I were to get a catless 3" downpipe from zzp or something would I have to get a tune? Car is totally stock by the way.
 


Well if you get a p0420 code, a tune will help or do the anti-fouler trick. I would also recommend the zzp o2 sim as a third option but at that price, I would just get a tune. better benefits.

Ok. Luckily I haven't had any codes yet since I bought it a year a half ago. I might buy some SD headers but that will be sometime in the distant future.
