Just did this over the weekend on my ‘08 Cayenne S using 4 jackstands. I really appreciate the video, I don’t think I would have attempted it without seeing all the steps involved. I’m not aware of any other video detailing this. A few suggestions to add: 1. If you don’t have a shop torch, consider buying a new secondary cat. The studs are extremely difficult to remove, even after drilling out. 2. Support transmission and remove crossmember from car before removing the 2 mounting bolts (16mm is also not a common size in most sets) 3. Spray header studs with liquid wrench using multiple applications and at least a full day
I’m glad you found it helpful. I only take the time to make a video if I can’t find one on the subject that will suffice. Good idea to add tips based on your experience. Would probably be less expensive to buy a small acetylene torch like I have than a new main cat and then you’d have it going forward (very handy).
I got my primary catalytic converter off rockauto for $350(was a perfect fit) and noticed the back one was listed at $281, which didn’t seem terrible. Having a torch would definitely come in handy on future projects though.

@@davidplathe Wow, that’s a good price!! That is definitely less expensive than the torch. Good tip!
Thanks for uploading this, I like to see something done before I agree to tackle the job for the first time!
Thanks for the video. I’ve got to pull them both. So far only one broken rear cat stud. Fronts come out tomorrow.
Nice wood block brace 16:26
Good luck tomorrow with the primaries and let us know how it goes. Fingers crossed that your exhaust manifold studs are in good shape.
@@pcardoctor5492 Got them out, no Broken studs! Got to be very careful putting in the new ones. The catalyst is exposed and could easily be damaged!
Is this the same for a 2012 Cayanne s hybrid??
I’m gonna do this myself never worked on a car in my life and I won’t go to a mechanic cause I know they’ll take advantage of my lack of car knowledge
