This is the second time that this has been happening. Noticed that it only happens when I use tiptronic (manual). First time I was driving hard then floored brake become light turned yellow. Few minutes later, a rotten, sulfur, egg smell came out of no where and my sister thought I passed gas (when I did not).
Second time that happened was when I dropped off my friend late at night, went on manual but this time I drove casually & normally and didn't go crazy. As soon as my friend got off, there's more of a burnt smell then with a hint of a rotten egg that took place in my car.
My car is 2009 and has only 83k miles in it. Read to a similar scenario online and seems like my catalytic converter needs to be replaced.
I worried that my car is internally bad, should I bring it back to Toyota (where I purchased vehicle pre-owned) for a diagnostic?
I'd appreciate any advises!

Sounds like normal smell during acceleration. A bad cat usually ends up being plugged and will cause MIL to light up. Sulfur smell (rotten eggs) is the normal process of the cat so unless you have other issues which trigger the MIL it is not a problem.
