Just delete that crap and run the smog pump directly to the cats via a heater hose. Keep the stock EGR hooked up since its external. The air injection stuff does absolutely 0 for actually passing the sniffer. Visually I can't imagine someone would notice its gone.
I junked mine right away when I had my 95 and it passed the sniffer with flying colors every time by swapping the stock pipe back in for emissions day.

Just because I give you advice, doesn't mean I know more than you. Its just means I've done more stupid ****.
