If you need to bend the pipe OUT, it is fairly easy to do.
Propain (map gas prefered) torch
fine sand for stuffing the pipe (can get it fomr Lowes/Hone depot)
Pair of heavy gloves for heat (naturally of course)
vice mounted to a bench
long 3/8 or 1/2 drive socket that fits over the header tube (and also a nice longish extension)
stuff the pipe with the sand and tape off the motor side so it wont fall out
chuck the motor side in a vise securely
heat up the pipe real good until it just starts to turn a shade of orange/reddish where you need it bent
slip the socket with the extension over the pipe and slowly and carefully start bending it out (while keeping the flame
moving over the pipe area)
when you get where you want it, remove the heat and socket and let it air cool.
the key here is take your time and keep the flame moving
Or you can call MACS products out in CA andask them to make you one to order.
