got a ? ive runnning catless for awhile and i have a ced for the cat.. ive been told recently that the ced will reduce the power of the motor ? any truth in this ?
first are you talking about the CEL (check engine light). and yes a catless downpipe will cause an catalyst efficiency code. but no it shouldn't reduce any performance of your car. it will only show the annoying code all the time without either getting it tuned out or putting in an O2 spacer to fool the sensor's reading.
but get the code scanned to make sure it is the catalyst efficiency code. if its something else then look into what that is but from what you describe its the efficiency code.
