Well you could have them mounted into the cats like they should be, with the O2 end facing the exhaust end not engine.
Actually, you have a Gryphon, so what are you worried about? Your O2 sensors sound be turned off as is, so any cat work you do you should not get a CEL. Or if you do you could at least turn it off in your Gryphon. And have Bill send an update file to permanently delete it if he has not turned them off, but i'm pretty sure he has.
And that way, if a cop ever stops you for your truck being too loud, when he looks at the cluster theres no CEL, and when he looks under you have a full cat-back and cats with O2s in them WITHOUT sims

The custom tunes from Bill should automatically have them turned off. The programmer itself with canned tunes wont, you need to manually clear them and everytime the programmer is removed from the truck it will need to be re-adjusted to turn off, same with your tire size circumference and gear ratio.

Yes you should be able to clear the code. With a custom tune it should already be deleted/turned off. Verify with the guys that know for sure though on the PHP Forums. After you get it done you should also get a update that you aren't running cats anymore for full performance advantage, Bill will modify the fuel settings minorly and you shouldn't see any energy loss.

The sun finally came out and the rain finally stopped. I spent about an hour making a nice fancy video, but the audio was cut on it due to copyright ****. So here's the raw footage.

Thanks man, I suggest an X-pipe instead of an H, and maybe short mustang tips. Mine doesn't have that Mustang sound I've been shooting for and I think those 2 changes would make it closer than what I've got.

I'll have to get a video of the inside under hard accelleration one day. Even while going down the freeway at 70 MPH, it's as smooth as butter and surprisingly quiet. That is of course until it downshifts.
