Right I know is been a while and just thought I'd give you all an update, the banging through the steering wheel and steering going heavy is due to when I accelerate in first gear and maybe second (not often) is the header is so close to the rack and pinion it is actually hitting, as it has wore away the heat wrap. Hopefully getting it to my mates garage to see if he can heat it up with a torch and gently pursued the header in a bit instead of cutting and welding a notch out of it as I don't want to go down that route. So to anyone thinking of getting headers just do a test fit on drivers side to see how close it is might need to modify it a little. But apart from that they are the nuts and gives the car a tottally different feel performance wise and an even better sound, I'll try and get some videos up soon as I'm doing a dyno day in mid November. Thanks for all the help and advice also
