p2195 and p2096
Another CEL thread I know. I just made my downpipe catless this weekend and are now throwing two codes. I know the first one is for the O2 sensor, and the 2nd one is fuel trim bank one- system too lean. Is this common after getting catless dp? I added the O2 extension on my downpipe so it's not in the mainstream. I also have infiniboost tune, just an fyi. Any help?
Nevermind, my exhaust gasket was crooked causing my car to sound weird and throw the codes, all fixed now.

Well that makes sense. The misaligned gasket was an oxygen leak. Too
Much oxygen was brought into the exhaust via venturi effect and the post cat otwo sensor read an oxygen rich state, meaning too lean. The cause was operator error, as usual, though, giving creedence to the theory that we make 90% of our own problems.
