    Does anyone have a recommendation for sourcing replacement insulation for the exhaust elbows. I don’t see them on the Seaboard site.

    Custom QSB Exhaust Riser

    Dave,

    You need to stand back 2-3 ft and post of pictures of the entire riser and the connection to the hose.. Maybe a few angles & perspectives…… What you have is 100% custom, and from the looks of the exhaust flange where it is attached to the turbo, I think you may have some other serious issues going on.. Best to REMOVE the insulation before you post better pictures..

    How about posting good pics what what you want to replace and of the exhaust itself.. That would be a start
