I would appreciate the following (loan of for a few weeks)
a) williams manifold (standard)
b) supersprint 4-2-1 manifold
c) williams cat
d) willaims centre section or equivalent system of the same dimentions
e) willaims back box or equivalent system of the same dimentions
Jesus has offered me a magnex cat back system so far, are there any differences between this and the standard in terms of shape & size?
