I had the cat converters removed and put an X-pipe on. Now my check engine light stays on. Does anyone know how to fix, or were I can buy "dummy" hego sensor plugs?

Well, you still need to run the O2's. You can't just remove them on a stock tune setup without making some adjustments to the computer via a custom chip. That alone will trip the CEL

WHat you need are called MIL eliminators. However they are no longer made due to the gov't making them illegal. You might be able to find a set used or make your own

Another option is turning the rear o2's off with a custom tune.
