    Been a bit of discussion about stainless steel manifolds and full systems. I have had a straight through system on A666 for 10 years, works a treat, never touched it. A member on here, Simon works with stainless all the time. He is the brother of Mat, who are both helping me with A69. Top class workmanship. I spoke to Simon this morning and he is more than willing in to fabricate and tig systems to order. The only drawback maybe availability of bends and tube in this present debacle. Give him a ring on 07852 612652 for a chat about what you may need. Paul.

    I have a Janspeed 2.8 stainless system to connect up to a Cosworth BOB, as I recommended in another thread use mild steel primaries for the exhaust manifold due to austenitic stainless steel as having a high rate of thermal expansion, low thermal conductivity and being less malleable than mild steel so therefore can crack. Swaymar did research into long 3:1 steel primaries but I don't have any dimensions for them.

    I made my own stainless exhaust using 2" dairy fittings and tube and stainless boxes from Ebay. the over axle part was a nightmare but trial and error i got there in the end. All welded with a cheap scratch start TIG,
    If i had to do another i probably wouldn't bother with a back box because its too quiet, but its done 3k miles this year, no problem
    If i get really bored during this lock down i might see if i can find enough bits to make a manifold too, but that will be a lot more complicated

    welcome indeed, you have images to share?
    Manifolds are a subject that can cause discord along the way..
    but it worries me that being a friend of Finn you may also not like posting photos of the fine work you're involved in..

    I have known Simon and his Brother Mat for many years, fine fabricators and Mig/Tig/ Stick welders. We need pics Simon! Paul.
