Has anyone experienced a foul odor from the primary cats? I have had my secondaries and resonator deleted for about 2 years now if that makes a difference. The smell usually occurs a few seconds after i go full throttle. I have 60k miles fyi. The primary cats going bad is all i can think of. On that note, is anyone selling a pair of relatively low mileage (oem) primary cats?

I have two sets of cats.

Check if anything is hitting them and burning.

Is it a burnt smell? If so, that's probably normal; especially after full throttle.

How many miles on each? I don't think they are hitting anything.

It's perfectly normal for it to smell like rotten eggs after going full throttle.

This is the perfect way to describe what I was trying to say.

I thought it was normal at first as well until it started happening every time and the smell became unbearable.

Like others have already mentioned, it's normal. If you don't want to smell it, don't flog it right before you park it. If you do a cool down run before you park it, you won't be smelling it as strongly.

I should have made my initial post a bit clearer. The smell occurs immediately after I go full throttle while the car is still moving. It literally fills the cabin with an odd odor. It's definitely not a rotten egg smell either.
