Is it not cheaper to have someone put the stock cat back on two times until you are not subject to testing than buying a race cat and installing it.

That is one install compared to to installs and two removals. Plus you will make more power with less lag. Turbos do not like back pressure at all.

The C2T final muffler is a great turbo muffler and a tennis ball will pass through it. It is just the pre-muffler cat that is restrictive.

Another option is to a final muffler bypass and keep the stock pre muffler cat.

Lastly, you could have the pre muffler part of the stock cat gutted but I do not know if it will help much.
