Thanks for getting back to me! They aren't the easiest to install its a little buried, nothing that you couldn't handle.
As far as power, it is minimal on some cars we have seen as much as 5HP. That is not what it is all about, it comes down to the ability to block dust particles from entering the engine. I did a write up not too long ago, you can view it HERE, it gives specifics on them. Overall the BMC blocks more pollutants and is a much higher quality filter that will really last the lifetime of the car if maintained.

BMC filters are $80+ on Amazon as well as other sites whereas K&N filters are discounted to around $50 +/-. What is the difference, if any, between the two?

More Observations
I've noticed several things since I had my secondary cats removed:
1. It took a few days for the ECU to "learn" there was less back pressure and my performance actually improved.
2. As the new pipes aged and experienced more heat cycles the V8 growl gets deeper and throatier, in a good way.
3. My gas mileage has actually improved, not much but it's better.
4. Hit the Sport button and watch out! Much quicker throttle response, acceleration and torque feel. It's GREAT!
5. Still no CEL or other sensor warnings.
This is without a doubt the best mod for a CTT. I think a tune will only add to the overall performance. Perhaps that's next now that I'm addicted. LOVE my CTT!

According to their website, for 2015+ they only list the GTS.

Will the GTS secondary cats work on the CTT?

Yes, the sport exhaust should not be an issue. I'll PM you now!

Here is the video of mine with the secondary cat bypasss and the sport exhaust. I am happy with the sound of the combo. In addition, now you can feel the car when you drive and in sport it's really nice. I think it was a good option. I believe I paid $3200 for both and they throw in the BMC filter as part of the package.

Sorry, but couldn't help but notice the Cayenne leaning to the DS. Mine is doing this again too. Durametric can't get her even.

Interesting tread, I am trying to make a deal for a new Cayenne Turbo with one of my local dealers. My guess is that I will still need a throttle booster since the drive by wire hesitation will still be there even with this installed.

That just opens the throttle faster...same as pressing the pedal more. You should look into a tune and performance intake plenum to help the small lag reduce. A tune on a turboed car will make a major difference.
