I have found these for a very good price through a US company but I cannot understand why they are going so cheap, even over here they are going for £465 which I though was rather cheap for headers?

OK so they may have only one slip joint on the headers and none in the up-pipe but surely this would have been tested in the research and development stage to make sure that they could with stand the stresses involved?

Is anyone using these currently or have any view on them?

Isn't Andy F running a set of these? Might be worth dropping him a line??
