I've had my off-road X-pipe, and Flowmaster cat-backs on for nearly 2yrs now, and still no CEL..... I did get a CEL at first, but after reading the OBDII code, i had a bad O2 sensor. But after further inspection, I pinched the wireharness between the block and tranny when I did my clutch swap... Repaired it, and cleared the computers memory, and the CEL has never come back on after that..
