dansk 2in2out muffler

[adamsison]

Hey everyone,
im planning to add either extractors or SSi heat exchangers + a dansk 2 in 2 out muffler to my 1980

this issue is my car has a 965 turbo steel body on it....

does any one know if the dansk 2 in 2 out muffler will fit? (link to pic below)

also does the heater make much difference, its an unusually long and hot summer here in australia and havent had the heater hoses connected yet.

any help/advice would be great
