I believe they are m6x30mm, but i would get them from the dealer, exhaust bolts are made different than a standard grade 8 or 10.9, a grade 8 will fatiuge from the heat and not hold, or most likely snap if you ever needed to be removed

Curtis, great to finally meet you also. Thanks for your help the other day. Jeff was able to get that connection sealed up with the existing bolts, but it seems he may have some leakage at the manifold to block surface. Also looks like the start of oil cooler issues.

This might help:
Riffraff Diesel: Up-pipe Reinstall Hardware Kit 99-03
These bolts will probably stand up to heat better than hardware store stuff.
