Risers and elbows

[smoothmove]

Wow...That exhaust riser in post # 16 looks incredibly sturdy....I'm afraid overkill.... I'd sure be concerned about the WEIGHT of that thing hanging off my exhaust manifolds...I note that on my old DD diesels there are supports for everything indicating to me that vibration stress is a real issue over time...
Also, are those protrusions for hose connections in the upper end long enough to get a good grip....or two hose clamps on each???

These are a specific replacements for the old cast iron Chris Craft riser which was a very good riser. In these older designs, the solution was often to throw enough iron at the problem to take care of the unavoidable corrosion which occurs. I'm still using my 41 year old risers today and they looked pretty good when I removed and inspected them recently. The stainless replacement is roughly the same weight as the unit it is designed to replace. The protrusions are threaded for a nipple.
