First thing I thought of when I saw the pictures.

Over scavenge you say? I can't wait for results!
Very interesting that a HFC would get that hot that fast. I was watching some info on how the stock cat did so well, but then again OP temp of your HFC seems substantially lower than the factory unit.

The EGT's drop very fast as the gas travels through the exhaust. Unless you have heat shields, header wrap, double walled pipe, or a coating, the temps while cruising probably drop over 100 degrees per foot. I did the EGT testing with my "empty" (non-deadened) expansion chamber, so the EGT's will be considerably higher with the new pipe I just built, which has the deadening material and perf-cone prior to the HFC.
EDIT: I would bet that the EGT would actually drop more than 200 degrees F per foot while cruising ...

I was going to wait until I had more confidence in my hypothesis before posting these results, but figured it wouldn't hurt to just post the graphs now. I'm going to hold my conclusions until later.

Had the opportunity to ride in Greg's car today and I must say I'm impressed! First, there is no drone with his exhaust. Secondly the acceleration is immediate and smooth throughout the gears. And this was on a 90 degree day with 40% humidity, impressive! I for one will be watching the progress on this very professional system.

It is a smoother and more usable power delivery.

Wow! Can't wait to see results man! Very interested in temps.do u think it may get to hot at any point or with it being so far back in the stream it won't suffer like factory placement seems to do IMO
I don't know how hot the OEM cat gets, but it is close to the engine for a reason. It's terrible for performance, but great for emissions. From what I've read, it's pretty common for a catalytic converter to reach 2000 degrees F, but the HFC incorporated in my mid-pipe is reaching about 900 F at full load / high RPMs in 3rd gear. It might exceed 1K F in higher gears with sustained high RPMs.
