Hellllllllllllo
Go and by some 2 inch poly pipe tomorrow and then you can take your manifolds off and bend the poly pipe with a heat gun all around all the stuff you have to miss and make fake manifolds
THEN take a picture of it, THEN chop it up into suitable bits that you can make with steel bends. Then make it
You might have to throw your poly pipe sections in the freezer so they dont go loose shape
, or fill them with concrete, or something : )
