I have no CEL with 200 Fabspeed cats, but I would love to go catless. Just don't want to look at the CEL all the time. I have softronic tune as well. Could I fix this with Durametric?

If you don't have emissions testing where you are you can just have softtronic turn off the rear o2s. I don't think a durametric will do anything but clear the cell if you get one. You can also try what I did with the extenders and steel wool.

 

Can you link these extenders (just trying to learn more here). Are they simply spacers to push the O2 sensors out a bit farther?

 

Yup, that pretty much sums it up. The "Catted" extender ones goes one step further to minimize Cel.

 

Okay, thanks for that. I am familiar with these from prior experience with Audis
