Congrats on the new purchase and call Fabspeed if you want to wake up the beast! We just developed secondary catbypass pipes and a Maxflo muffler system with deluxe tips. Sonnen Porsche in San Francisco installed the complete package and took a video and I have to share this with you all, very mean even with a bad microphone.
The exhaust system is very similar to the previous Cayenne Turbo, direct replacement with a lifetime warranty. Combine this system with the EVOMSit ECU plug-n-play system and the power gain is immense.

looks like great choice to me.
i think the espresso / cognac is HOT.

 

I can't Rep you yet, must spread around...
