I have heard otherwise. I've been advised against installing them if I forego a tune. I'm in love with the idea if you are right, so I hope you are lol. But can anyone else confirm? I DO NOT want a CEL. |
You always have the option to just install the lower down pipes instead of upper and lower and it wont give a check engine light. The lower installs after the o2 sensor.
