Hi I've tried to put the kit on my exhaust manifold(e46 330cd) but there are two point to be complain.
1) the bolts are too long and come out from the back, this is a trouble with the first two and last two nuts that will be locked on manifold. (should be 20mm instead of 40)
2) the metal grade related to the bolts is lower thant 8.8, and for this kind of application (temperature above 600 degree) is not the properly choise.
The shipment was very fast.
