I don't have any cats at all. I'm talking about my rear/downstream O2 sensors being off so that they don't tigger my CEL for cat inefficiency. They did indeed switch to 2 cats during the 05 MY.

From what I remember Bill from PHP did some testing on a 09 5.4 3v with his version of gotts mod. According to the sheets I saw he got a solid 7 horse and torque at 3500 rpms. So yes not a lot and might be hard to notice, but for 20 bucks it's better than nothing.
I did the gotts and notice better throttle response but that was it and it was with canned tunes. Haven't ordered custom tunes yet.
I've debated on getting a used aftermarket intake that is all closed box to get rid of the panel filter and go conical, but for the price new I wouldn't waste the money.
