Hey everyone. I have an extended warranty on my 2k1 Civic EX and I have already ordered a new OBX cat-back exhaust and an Injen SRI for my car. I dont want to void my warranty and when I called the service department concerning my warranty and installing these aftermarket things, they said as long as they don't mess up your engine. They said something about if the exhaut messes up my O2 sensor then it will void my warranty. Well, will a catback exhaust mess up my O2 sensor or not? They didn't say anything specific about the intake, but will I be taking a risk of messing up my engine with an intake or not? Thanks for your feedback!
