Deleting o2 and cat question

[Chris.G.Jr.]

So I already have a couple magnaflow mufflers to run dual exhaust and i wasnt sure how to really set it up.

If i delete the cat and o/2 sensor won't it throw a code?
If it does would an exhaust shop or any mechanic shop be able to tune it out or would i actually have to get a tune?

I don't think the tbi or any obd1 car/trucks car about cats.since they don't have o2 sensor after the cat.

Yea my '94 didn't have a light come on when I had a plug in the o2 sensor and no cat. Should be fine.

hmm may end up cutting the cat and running straight pipe to a magnaflow dumped after axle

Don't delete the o2. The engine adjust fuel based on it. You have no post cat o2 so just take the cat off.

^^^^ ditto. You need that o2 sensor for fuel trims

It won't throw a code unless its an OBD2 (which it's not though).
I'll agree with the others who said don't delete the 02... you need that
