Resonator for Cat?
If I put in a resonator in place of a Cat for better exhaust flow, would the engine light comes on?

Thanks

The Celica's cat is already pretty high-flow so you should just take the resonator out. thumbsup

so just take out the esonator and not the cat??
but that would create a lots of noise?? I was thinking I can run 2 Resonator instead of 1 cat and 1 Resonator

i wouldn't worry about taking off your cat, as ^^^ said, it's already very minimally restrictive. i guess it depends on what you are trying to do here, make it louder or more power? there's something in the install guide about removing the butterfly clip, that does a little of both, maybe that would be a better option for you, i don't know much about the resonator or how replacing the cat with it would work, sorry wave

Taking off your cat will make it louder than taking off the resonator.

Just thought if I ended up not liking it, I could put the Cat back in. Whereas if I take out the cat I have to weld it back on. So taking cat out would not create an engine lite then?

Thanks

yes cause it has a o2 sensor on it you would have to get a o2 sensor simulator.

also don;t know about where you live but its illegal here to do it cause of emissions
