    I’m thinking about getting some headers for my 2002 IS but i don’t know anything about o2 sims or how the sensors even work, if i were to install the headers without a sim will the car even turn on? Or will it turn on but my mpg will go down a lot and i’ll get a CEL light, any help would be...

    I have a clogged cat that's in the manifold(first 2 cats) and I called around to see how much to fix and the shop said 1800 to replace the manifold etc. I'm assuming oem parts , but what about just getting headers and deleting the cats? What about the sensors? What's my best course of action...
