Car could be running too rich. Do you have a cat still? Any changes you have done recently? Are plugs and wires new? Any other info can help. Is ther check engine light on?

Smells like gas, as in the rotten egg/dead body smell that they mix with natural gas so you know you have a leak?

Not 100% sure on this, but dont catalytic converters smell like sulfer (eggs) when they are going bad?

Based on your profile you're still running you catalytic converter. Most likely your car is running rich which causes your exhaust to smell like rotten eggs. Mercaptan which they add to natural gas gives it that same rotten egg smell. Check your O2 sensor, it could be going bad causing your car to run rich.

Yes, when the cat is going bad they smell like rotten egg (sulfur). If you still have a catalytic converter I would say its going bad, and you also may have a leak. Most likely the catalytic converter is bad especially if you run the car pretty hard on higher boost levels then stock.

ALso, did you put in larger ingectors without doing any form of engine management to compensate the more fuel going in?
