No cats-> Check engine light?
Hi,
For those who have runned their cars without cats before (for off road use of course), have you ever had error codes/check engine light come on after driving for a while? Just want to hear your experience. Thanks.

IF you don't run rear sims or get a tune, you will most likely get P0420 and P0430 after about 45 min engine run time. Not a big deal but is annoying. Bank 1/2 TWC eff. error. I used to get it before tune.
