ever since i picked up the ss sc, i noticed the exhaust has a rotten egg smell to it...my boost is normal and i do not have a CEL....is a little smell normal?
I don't have an SC, but I have a possible suggestion... Around here, the gas from Shell smells like rotten eggs... I know, weird, but... its a thought...
The smell is unburnt gas hitting the cat. I get it occasionally when driving the car hard. Ours cars do run a little rich so a slight smell after a hard drive is prolly normal.
