Default Exhaust smells like fish?

So yesterday while driving I kept smelling rotten fish and it smelt like it was coming from outside so I thought nothing of it. Well when i go out of my car it REALLY smelt like fish and it was coming from my SC, so I looked around to make sure nothing was out of the ordinary or on fire, While checking things out I followed the smell and it is coming from my exhaust...............WTF lol, what could this be?

Today the samething happened, as soon as my car got warm the fish smell came back

LOL. The exhaust coming out smells normal, the smell seems to be coming from the 2 cat converter area..............bad cats?

^^^+1 also have you noticed your performace going down a little. Also if your converter is plugging it could cause spark knock so just list out for it but chances are you should be fine for a little while if you can't fix now
