Additionally, the gas residence time within the catalyst is increased. These factors contribute to better emissions performance. We have datalogged the catalyst performance values monitored by the OBDII system and compared them with the performance of the stock catalytic convertor and a catless DP, we know what the range of values should be and we dialed it in. Our test car has gone thousands of miles with no CEL. On a fully catless DP we are able to trigger it within 5 minutes of driving. We decided it was time to release it to the public so here it is! Give it a try and let us know what you think.
Thank you for replying to my PM.

For the catted dp, do you guarantee there will be no CEL triggered on a stock set-up? What do I do if it happens when I install your catted dp?

When you say 'Our test car has gone thousands of miles with no CEL.' is that completely stock? Have you tested using a piggyback or flash then revert to stock? I'm contemplating my options when it's smog-check time... do you have any insight/recommendations?
