Hey!
Last weekend I wanted to quiet my exhaust. I was running a 2.25 cat back piping to two magnaflow race series mufflers. I went to my local exhaust shop and had a 22" magnaflow resonator put on just back of the cat. The next day, after driving 200 km (120miles) my engine light came on. Do you think that this was caused by the resonator or something else. Oh yeah I have a 2002 Ecotec with 90000Km's. Thanks for your help.
