Emi are cheaper for a reason. SM are far superior to emi. The ones MT posted are the best performing and they will powdercoat them in different colors.

I have a pair of SSM's on my small blocks and could not be more pleased with the quality. I spoke to stainless marine and the owner before ordering and they were a pleasure to deal with. When I placed my order, they were one riser short in inventory, the owner made it and overnight shipped it to arrive one day behind the original order. Hard to find that service these days.

Aren't the EMI units having material problems these days? I thought that I read that folks were having failures on even newer units because they started getting raw materials from China. I could be wrong but just mentioning it.
