Looking for both part numbers and sizes of the primary muffler clamp bolts/nuts (the clamps attaching the cat on one side and the secondary on the other). As well as the screws attaching the heatshield to the cat.

I have just ordered the PET cd, hopefully I can start looking this type of info easier in the future.

Thanks in advance,
Puma

When I took my secondary off to put on the g-pipe, I just swapped all bolts/nuts on the exhaust clamps for stainless thate were about the right size - cheaper than Porsche parts and will be very easy to undo the next time.

What is the outside diameter of the washer(s)? Trying to figure out McMaster equivalents...are the M8 bold fully or partially threaded?

The bolts are partially threaded and the washer specifics for the clamp are 8.4x17.3.1. The washer for the bolt on the cat just says b 6.4.

NOTE - The part number for the washer on the bolt for the cat is N 011 666 7
