Anybody have any experience with BigDaddies Mini Cat adapter in preventing CEL's. I'm looking to add a 200 cell downpipe to go with my custom exhaust. The unit is a spacer for the downstream lambda sensor, but appears to be unique in that it contains a platinum and rhodium honeycomb to alter the exhaust gases passing through to the O2 sensor.

Since PAW is close by I know I can get a tune to delete the CEL light but I'm hoping to use the BMS JB+ instead once it becomes available. The Delete-R is also an option for my 2011 MCS but this is less expensive.
