So I plan on cutting out the cats on my R32. Not for performance but for sound. So couple of questions I have.
So for design I plan on matching the factory diameter of the exhaust. once cats are cut out I will put in place steel and hold in with an exhaust clamp on each side. such as a clamp like this.

so first question is what is factory exhaust diameter
next question is should i space both 02 sensors or just the one post cat. (yes i know there are 2 cats so everything is double)
any suggestions and insight are appreciated
