Are there any products such as intakes, exhaust, etc. that could increase the horsepower in my 06 Cayenne base, making it faster?

 

I feel your pain or your thurst Philly_Paul,

I have an 04 Cayenne 3.2

what I did to get more ***** outta mine was;

1- changed the Oil from Mobil1 to MOTUL 8100
2- Upgraded the CAI filter to AEI
3- Deleted the 3rd catalyst converter on the single pipe after the HEADERs
4- Custom Mufflers and Retained the OEM TIPS
5- Koni Lowering springs

The next steps are maybe's depending on the feedbacks
6- software upgrade from.....? can not remember the site but it was in excellence magazine
7- Brake Upgrade to C/D or slotted rotors and better pads, steel braided lines
8-

but that's what i have done and felt the difference ;-)
