16V manifold successfully modified to fit with inboard discs
Took a bit of time and some head scratching but not too bad too do in the finish. Turns out that the outer / rear cylinder pipes clear the inboard discs and just the inners/ front pipes need rerouting.
Cut the inner legs off about 75mm before they go into 2. Welded a straight section on, to run pipe up inside of disc, other std pipe runs up disc outside.
Cut pipe about level with leading edge of disc.
Elongate the holes in the manifold flange to give extra turn and cut pipe off about 180mm from head.
Use a straight piece of pipe to get to by disc then cut a bend out of the pipe that had been removed to give a smooth rad bend between pipe from head and run down into manifold.
Weld it all together
