Will installing a cat back exhaust trigger my check engine light?
I just purchased a Mishimoto cat-back exhaust system. I have not done any modifications on my car so far so this will be the first one. I will not do any modifications to the catalytic converter and will keep it on there. All I am planning to do is add the exhaust system but I am worried that it will trigger the CEL.
Anyone had this modification done? If so, did it trigger the CEL? Thanks in Advance |

If you keep the O2 sensors, AFM & NPP valves it should be fine.
