Any check engine lights?

Yeah, The nuts were sized to the studs. So, when I unscrewed them, the stud unscrewed from the head. I figured that I might as well replace them all. No major complications. I did have a shop cut and weld new flanges on the mid pipe to make it fit. But, I was expecting that. For the check light, I flashed my DME with the Euro 2 tune. It deletes the post cat O2 sensors and the secondary air pump. No check light for me

Do you have emissions testing?

The tune will show up on an emissions test as a "fault" (for lack of a better term).

I have headers sitting in my living room for my Z, reasons for the questions. I plan on using mechanical cat simulators and just simply leaving the sap disconnected from the exhaust. I guess I need studs too
