I was wondering if anyone has attempted to dump there exaughst just before the CAT.

I have a wide band sensor installed in my downpipe about 2.5 inches before the flange that connects to the CAT.

Since I use my car purely for racing, I get tired of having to drop the whole exaughst system when I have to fix things, and was curious if I dump it that close to where my wide band sensor is, do you think it will mess up the readings?

Any one help out!
