I am thinking about leaving my stock exhaust system but adding headers and electronic cutouts so my question is will I have any problems with performance or mechanically running the car with open headers and no restriction?:grouphug:

Yes, don't do it ahha. You'll foul out your o2's, you will have no backpressure(no low end), and in the winter you can break valve springs.
