Neither will affect performance. Is that what you're getting at? Evap delete would help make it simpler to do a FWI, but it'* simple enough to relocate it or bypass it on your own.

Rear O2 delete makes your choices for high-flow cats simpler and slightly cheaper.

Although. Recently some of us figured out how to keep the evap canister looking decent and I had a rear O2 bung welded in.

Both were cheap and easy overall.

well after i welded my cat on as soon as i started the car when i was finished i get a evap code along with a driver 6 code
which i has come to the conclusion that when i welded the cat on that had somthing to do with it because i didnt disconnect the battery

Driver 6? that'* not an OBD2 code.

You didn't do anything by welding a cat on. Plus..most codes take two drive cycle occurances to illuminate the light.
