As much as I want a Cayenne TT I just couldn't give up my 535xi wagon. So I ordered silicone inlets, bigger front mount and downpipes for it. Should put me in the high 400's if not low 500's and at that point the BMW is same horse power as cayenne and it will get its fun factor back. The trade off from wagon to cayenne wasn't great.
I'm still going to get a cayenne but I'm going to get an S for 5-8k pay in cash and have it for winter
