those of you with exhaust Options

[cg97]

for those of you with exhaust, without a cat, did the CEL come on? or do i just need a header with 2 sensor spots? i know some guys who did the whole header exhaust thing and they had to put a high flow cat in, is there a way to get around a cat? thanks

Celicas have two cats. Take one out and you should be fine. I still have both though. No CEL's. If you have an aftermarket exhaust manifold then you will need to weld on a new bung for the second sensor. More info here clicky. Read step 10.

Yeah but your car is OBD-I. His is OBD-II. o0black0o's car threw a cel when we did his even with both o2's hooked up. I've seen other cars do that also.

And yes mandrel does mean a difference and just bigger piping isn't going to make that up. Especially if you are talking about on the header. You don't want a crush bent header.
