I just bought an 06 Turbo S and read that this was a must do. The car seems too quiet to me as I previously had a 911 with a factory sport exhaust and loved it. I looked under the Cayenne and only could see one set of Cats. Are the primary cats closer to the motor and hard to see? My 2nd question is has anyone just gone down to a muffler shop and had them weld custom pipe on instead. I noticed on another thread someone briefly mentioned that on an 04 and said it worked out fine. 3rd question is has anyone recorded an 06 turbo S after installation? I'm wondering how much better it will sound. Some say minor change and some say its much bigger difference. Thanks

Milltek
Thanks for the reply. Luckily we don't have emission testing here but everything I read says the primaries keep it legal. I just found these made from Milltek at the best price yet. Anyone tried this brand? Still would love to hear an 06ish Turbo S with this conversion if someone has or can make a clip. Thanks

FWIW, a crossover (x-pipe) was deliberately not used by Porsche on the Turbo Cayennes. See attached for a description of the factory exhaust systems.

I had my full exhaust done at a local performance shop and am very happy with it. It only cost $750. They removed the secondary cats and just ran pipes back to magnaflow mufflers. The sound is amazing and theres nothing like the crackles on downshifts. It is drastically louder than stock, thats for sure. No drone or obnoxious cabin noise though, still quiet inside with the windows up.

What's in the picture is considered an H-pipe. I'm pretty sure porsche was not looking at max performance also when they designed the exhaust, more like max noise reduction. The exhaust I am having fabed is a full 3" system from turbos to tips and what I am after is max performance not DB levels.

Here are Hank's pictures of my build equipped with the supersport exhaust and fabspeed tips. I have about ~40 miles on it and it sounds mean! Definitely has more bark and aggressive-ness than what came off. Hank is working on uploading some sound clips/vids, but I'll see if I can get some this weekend. The cold start-up cycle this morning gave me goosebumps! 
Hank's guys did an awesome job on the fabrication and fitment. I'm also told Primaries and Secondaries (2.5" and 3") are ready for shipment, as well as the mid-pipe. My setup is Primary deletes, Secondary deletes, 3" mid pipe with X-pipe, Supersport mufflers, and Fabspeed tips.
