I have an EB 02 Z06 on order and one of the mods I am contemplating is headers. I have heard great things about the quality and power potential of the TTS headers on a motor that is mostly stock.
Here are my questions: Are these headers coated inside and out (in my previous experience these coatings make a substantial difference in reducing heat and improving thermal efficiency); and if the '02's still have the pup or pre converters, will removing these cause the car to fail emissions testing? We have fairly rigorous testing here in Northern Va, car on dyno, different RPMs, etc.
Thanks for your help on this!
