hey guy, i have a header i wanted to install on my 94, 7a-fe, and it has 2 cats. with the new header i need to knock out the first cat. but from the engine it goes o2 sensor, cat, o2 sensor, cat, then just exhaust. i was wondering if keeping the o2 sensors in the same spot and taking out the first cat would do anything like make it run worse or anything even as little as the check engine light. im from pa, and we dont have emissions testing so im not worried about that, just the fact of re-selling it if i ever decide to, or just general concern. any advice would be great. thanks!
