Sulpher smell under hard excel?

The past few nights on the way home from work, I have smelled a strong sulpher odour while doing a few full throttle pulls. Has anyone else smelled this, or am I just crazy? What could cause this if it is the car?
 
It could be your cats. You might smell them more if your car isn't fully warmed up.

Save the dawn for your dishes!!!
its your cats. factory tune? mine used to give me that smell when I ran the trackey and the idle kicked in. I dont have cats anymore nor the trackey so all I smell is that sweet odor of E85 :)
