Just open your hood and look. Does it look hard or easy?
PS You can look at some taylor wires they make red 10mm wires that look bad ass!http://www.brothersperformance.com/shop/mustang/tay79257.html
I wanted to do the same thing. Use my 70mm FRPP TB on an Accufab plenum. I dont really want to ditch the 70mm FRPP cause I paid $180 for it. If some sucker would buy if off me I too would get the full Accufab setup.
With the Hookers you have to use their matching x-pipe. You wont be able to run just any old mid-pipe. This is why you can remove the trans with the headers on the car.
