hollowed out cat/CEL problem...
well i decided to hollow out my cat yesterday and then today i noticed my CEL came on...just curious if i should get an O2 simulator or if there are other solutions?
it actually doesnt sound like poop. i have an apex n1 exhaust on there which was loud, then i turbo'd it which made the exhaust sound non existant, but now it has a little sound to it but nothing bad
