The 7 bolts have a weird pattern. I had to order a tap and die from amazon.

I believe it is 11mm by 1.25. But do a little research. For the *head bolt thread and pitch*.

I'm a bit surprised no one else has posted this up as it has the answers for everything except the j-pipe: http://www.dsmtuners.com/forums/frequently-answered-dsm-questions/304059-what-size-bolt-screw-fastener.html

OEM j-pipe bolts are M8 x 1.25mm pitch x 20mm long.
