The test car has had the high flow cat on for ~2 weeks now. It is daily driven ~45 miles each day, plenty of time for the car to be in closed loop mode & monitor the cat. The OBDII only needs 2 engine cycles & ~30 miles of closed loop mode to throw the CEL. We've passed those tests w/ flying colors.

So has anyone here installed this yet?
I'm primarily interested in whether it will (1) throw a CEL on a 2006 model and (2) reduce drone on an aftermarket exhaust.
This sounds promising...

Yes, it will quiet down the drone of an aftermarket exhaust vs. test pipe. If you are comparing our HFC vs. the stock cat, they would sound about the same. Ours would be very slighlty louder vs. the stock cat.

I installed mine this morning and drove the car around the block. No CEL so far, no TP smell whatsoever, and it provided a subtle but nice change in the tone of my SuperSprint exhaust. My butt dyno is out for repair, so I can't comment on performance gains.

2) louder at vtec
3) it won't make it smell like a test pipe
4) reduced weight

2 - No, when compared to a test pipe. Our high flow cat will actually quiet down the car very slightly vs. the TP. Compared to the stock cat, YES. It will make the car sound more agressive during all throttle positions.
3. No. Should not have any TP smell.
4. YES. BIG weight savings.
5. YES. Should perform within 1HP of a test pipe. A test pipe should add ~5HP. Our's should be witihn 1HP.

If you are comparing to the stock cat, ours will make your exhaust slightly deeper and very slightly louder.
