1990 31' Excel, install of Stainless Marine manifolds?

[jdub]

Putting new exhaust on my fathers 1990 31 Scarab Excel and was wondering if anybody on here put Stainless Marine manifolds on. If so, what size risers did you use to meet up with the existing holes in the transom? I figured they were standard bravo risers (getting the long ones) but not sure. I already junked they old cast stuff and don't remember if they had a spacer in them. As always any help would be great!

jdub, when sourcing exhaust for my boat I called the companies offering a system, or components of interest. All of those called asked me of specific details, measurements, etc. so the correct system could be had, or compiled. I would think the same could apply in your case.
