Last week I installed a Mac Prochamber and Mac Cat-back on my 97 GT. The Pro-Chamber uses all o-2 sensors etc. and deletes the Cats. Yesterday my check engine light came on after about 300 miles since the installation. I believe this exhaust set-up is what has tripped the light but i would just like to know if anyone could assure me. Thanks to anyone who can help.

Yes, you are going to need MIL eliminators or a computer tune to turn off the light.
