Twin Turbo '74 Duster

Guy,
I bought a header kit from JEGS for $119 and flanges off ebay for $35..
Cut the bends you need and go. Use a mig with .023 wire with slow wire speed and 2/3 power. Just make sure you fab a bracket for the turbo(s) and mount it to the engine. Don't put the weight on the headers! Mine looks crazy but it will work!
