Default HF cat smell.

I changed my OEM for used stillen HFC about 6 months ago. Lately once a week I will smell the infamous sulfur smell while sitting at the red light. A few months back I installed a used after-market agency exhaust. I have K&N drop filters. I drive pretty normal and use Shell gas med/high grade. Is this a computer problem?

This burnt exhaust smell is normal with high flow catalytic converters installed on your 370Z.
