Cmi exhaust headers

[ryanwilson277]

I have a 1997 5.7 mercruiser engine in my 1982 checkmate eluder.
My exhaust manifolds and risers need to be replaced, currently I don't have the hatch on my boat because my boat was designed to use log style manifolds and risers and the stock 4" risers and manifolds are too tall. I'm looking at getting the cmi headers part number 13157 or 13156 because I can hook to my existing exhaust. I found dimensions for the cmi exhaust but I can't find what the dimensions of the stock exhaust is. Anyone with experience with these cmi systems, help would be appreciated. Thanks

Teague marine is CMI's largest dealer. CMI also has a good customer service.

Merc installation drawings have dimensions

I notice Teague marine doesn't have them in stock, best price I could find was from west coast offshore (as long as the shipping isn't horrible)

I think that the cmi headers still might be too tall, does anyone know the dimensions of the stainless marine manifolds and ss risers? I looked on their site and couldn't find any info
