Rotten egg after WOT
I have an 08 with 85k. All stock except joez Intake. Last night I had a strong rotten egg smel after doing a short WOT pull from about 40-70. I know this smell has to do with the cats but does this mean something is needing to be replaced or is this a build up that goes away if it push the car more? I tried it again a few hours later and got a sorta burning smell that I've had once before but no eggs that time.
Aside from needing to drop a full headers and exhaust system in what should I do?

I'm not sure if it makes a difference, but my F did the same thing after sitting for awhile. I recently installed full exhaust (w/ no cats) and it smells worse than before so I ordered some hi flow cats that I hope will resolve the rotten egg issue. I will let you know

It's normal. Sulfur (SO3) builds up on the catalytic converters during rich conditions and then that is released when WOT with leaner conditions (hotter exhaust gas temps.) heat the plates up in the cats to catalyzing temperatures. What you're smelling is hydrogen sulfide (H2S) and it'a actually a sign that you're emissions system is operating at a highly efficient level.

Gasoline currently doesn't have sulfur limits like low sulfur diesel does... the smell is normal as stated above.

Instead of taping these up, I would try to purchase new parts first.
I've been thinking about this post for the last few weeks as since the temperatures drop, I've been smelling this more than usual since I've had this car for the past 3 years.
