Greetings,
Inspired by EDgineered and others, I am planning to install shorty headers on my C55 soon. Could anyone help with part numbers for the correct copper nuts and replacement studs? I would also like to try and get part numbers for the manifold collector studs, nuts and gaskets.
I have not found a related thread after considerable searching. The only part number for the nuts that I found is 0009902552 but I am not sure this is correct.
Thanks for any help the experts can give.

I'm not sure of the parts #s but the shorty headers I have came with manifold to pipe studs/nuts and exhaust manifold gaskets. I reused the stock manifold to pipe bolts and the factory studs and copper nuts were in great shape, too. The factory gaskets were very thin due to the precisions of the factory flange so I used the supplied gaskets with the headers I got.
I would suggest calling a dealer and asking for the part #'s.
The part number for the copper nuts is 1121420072 (M6) and the gasket is 1121420180. I don't have the part number for the studs but they can be reused or get something that matches the M6 copper nuts.
So I'm about to order this hardware since I'm getting the Kleemann headers, but I'm finding slightly different part #'s than you guys. I think C55 only uses 2 gaskets, one on each side with all 4 outlets on it. Just wanted to add what I found:
Manifold Gasket (same for left and right), qty 2 - 113 141 09 80
Exhaust Manifold Nut, 8mm (header to manifold), qty 16 - 120 142 00 72
Exhaust Nut Split Collar, 8x1.25mm, 12mm hex (for the flange connection right after primaries to the downpipes), qty 4 - 000 990 32 50
This is from looking them up on RM European. When I called the dealer for the nuts:
Exhaust Manifold Nut - 112 142 00 72 - same as what Lenin said, only difference are those first 3 numbers, I'm thinking they may be the same part
Exhaust Bolt for Flange Connection after primaries, qty 4 - 170 990 00 10 - can't find this anywhere online, may just have to hit the stealership for these
Why do you need 170 990 00 10 with a Kleemann headers? Wouldn't the primary cats be deleted?
Need to be able to connect the headers to the downpipes, and turns out there are actually 3 bolt holes on each side so 6 total. I'm sure I could re-use the ones in there but just in case they are so seized on that they strip or something I want to have them handy. Plus I may just replace them all if they are in bad shape so they're nice and new.

Mine came with bolts and nuts from Kleemann. Not sure if they still do it. Give them a call. You may not need these bolts. Unless you are getting the used set above. Then measure thickness of both flanges and get the correct stainless steel bolts. The ones from MB may be too short.

Yup, used set...I went ahead and just bought 45mm, 50mm, and 55mm in the right thread size figuring one of them would work. They're so cheap, plus I needed an extra $5 to get to the $75 free shipping on RME
