Hell, it's so easy you don't even need a template. Pick up a foot of 1/2" flexible copper, bend it to the desired shape so it reaches from the header to the intake (you'll have to cut it to length). Cut the ends off the factory tube so you keep the flare to seal it up. slide the factory nut and flare over the tube, put a feril over it (needs to seal against the end of the factory tube since it's a smaller diameter tube), and tighten it up. After a few heat cycles, the copper discolors and you can't even really tell it's copper, so it shouldn't stand out to an inspector. I think it cost me around $6-8 for everything to do it.
