What grade bolt for exhaust manifold?
I've searched and found that the exhaust manifold studs/bolts are 10mmx1.25 and you can use 50MM ~ 60MM in length to try and catch the extra threads in the hole......but what grade bolt should I use? Grade 5 or grade 8? (metric equivalent of course)
Thanks.
Thanks.

There are two bolts, btw. But, they're only for the manifold plates. Otherwise, I concur...use studs. 4t for non-grooved.....6t for grooved. The groove will be on the end of the stud, if there are any.
Edit: I'm pretty sure it's 4t on the exhaust. 6t would have be for wheels studs.
