Im looking for a 1969 GS 400 metal heat stove pipe that attaches from the exhaust manifold to the air ram air breather.Thanks Martin
I've used a 2" X 36" hose from RockAuto on my 1970 GS 455. More Information for GATES 28090 (rockauto.com)
I know the 69 350 and 400 stove pipes for the GS breather are different. Not sure about the pipes for standard air cleaners.
I used the "Briz" technique; his tip anyway... a standard 350 stove pipe and made a short extension piece to fit the added distance to the ram air cleaner . You can get it made for cheap from an exhaust repair shop. The technique is called "swedge" fit extension; just paint it to match the stock unit and it looks perfectly acceptable unless you are going for factory . I believe my extension ended up being about 4" long. Let me know if you have any questions. The EBAY ones shown above are the standard / non GS length.
As mentioned above the GS 400 one is longer both of these look to be the more common 350 one . If you want a 350 one message me.
It would be good to have an example of each to compare. I think there is a unique 69 GS 350 one as well. I thought I had one but it was the more common 68 350 4bbl one. ( I think I have 3 of them now trying to chase the 69 GS350 one)
Here is the standard 350 heat stove compared to the GS 400 one I don't have an extra GS 400 heat tube but this is what you are looking for.
The 400 stove pipes and Rad shrouds is like a buyer beware thing. Most sellers on Ebay always try to pass of the 350s for 400s
My apologies fellas I have the stove and not the pipe ..... sorry! Do have a nice bare set of 68 400 heads if anyone’s interested ? Look to be virgin. Pm if interested ! Massachusetts
