Awful smell when max acceleration?

Rotten Eggs
The smell of rotten eggs is due to a compound called hydrogen sulfide. This comes from the small amount of sulfur that is present in the fuel. Normally the sulfur is converted to sulfur dioxide, which has no odor. When the converter breaks or the filtering layers have worn down inside the converter, the sulfur is not transformed into the odorless form. Therefore a strong rotten egg smell is produced. Another possible cause for this smell may be that the converter is plugged. Unfortunately you cannot repair a converter but need to have it completely replaced. Two other causes of rotten eggs besides a broken catalytic converter include an engine that is running too hot or a broken fuel pressure regulator. You can easily deal with the fuel pressure regulator by replacing the fuel filter.car-exhaust-smell-understanding-where-the-problem-lies

Wow, what a coincidence. I don't drive my car near redline often, but I decided to be a hooligan tonight and ran around a bit. I noticed an odd smell maybe 30 seconds after accelerating - was going to chalk it up to something outside, but I doubt it was a coincidence. Would this happen on a car with as low as 3700 miles?

not sure but I changed my oil using Penzoil Ultra plus Technology and it stopped the smell. Also it made my car perform way smoother and responsive . They claim it's 99.5% pure oil compared to the purity of others which is around 70-85%

Yep oil does help with that too, expensive brand Synthetic oil like Mobil 1 , Amsoil, Castrol, Penzoil, i've been using Mobil 1 Synthetic only for almost 20 years. I know a lot of guys driving Luxury cars but change cheap engine oil like 20$ per 5 litres in mechanic shop and whenever their car break down they go blame to the car maker, i remember the Volkswagon and Audi 2009 model stated under the Hood "Use 10w-30 Mobil 1 Synthetic oil only" .

Dude just go to an empty area without people and traffic and run the car hard like a drunken baboon. Redline it and drive it hard. Check the oil first and have fun. Sometimes a good cars likes to be rode hard and put away wet.

Do let us know what happens...I'm curious if Lexus will replace the cats...
Out of curiosity, what type/grade of fuel do you use? There is a possibility Lexus will also ask and recommend you change fuel stations/grade first.

If it's really bad (like mine was) and you've tried different brands of gas, you may be able to get the cat replaced under warranty. Ever since I got a new cat, I haven't smelled the rotten egg smell under hard acceleration.
