No emissions test in FLA i believe, didnt they do away with that??

I say this, because my cousion did a straight pipe on her mustang and i asked her about testing and she said there was none!!

If you're gonna hollow it out, make sure to bypass the O2 sensor that's located after the cat or even if you get a high flow, do something about that O2 sensor. Otherwise, you'll get CEL problems, also I heard that if you hollow it out and have it kind of like a straight pipe, your car may have back pressure problems. Better to have a high flow I'd say.

I would also go with the Hi-Flow.

btw, Chicago has unpredictable weather. Snow one week, rain the next, warm after that, snow again.

just keep it you get no performance increase from a high flow/gutted/no cat not to mention your computor wil not like not having the 02 sensor

I thought I'd heard the stock cat on Celica's was already pretty high-flowing? It's there for a reason, so whether you live in a state that has emissions testing or not, do us all a favor and either keep it or replace it with a high flow cat, don't just remove it or hollow it out.
