Just done the same job and I managed to force the pipes up past the bracket
by straightening out some of the bends, this worked but the end result is'nt the best looking job I have ever done. I realised afterwards a better option would be to cut each pipe and fit them in two halves making the join with in line brass pipe connectors. I reckoned a suitable place for the joins would be in front of the left hand rear wheel. Weigh it up and see what you think and best of luck!!!
