I am not slagging these products but I tried to fit these to a Glanza last weekend and they don't fit.With the manifold it is impossible to get one of the nuts back on even tried to fit the stud as you would a bolt but to no avail.The de-cat pipe is a similar story one of the nuts just hasn't room to fit.I would not fit parts like these unless i can get all the original nuts and studs on.It would be so easy for the manufacturer to rectify these faults.
