I am assembling a mk4 roadster with a 2004 mustang gt engine. I have a set of new FFR J tubes and stock side pipes. I have a set of factory manifolds and others from auto part stores. I am trying to determine which is the best combination. Does anyone have a sketch that would show the proper height and location for the side pipe flange? My rolling frame has stock wheels and tires and I need a way to be sure my flanges are close to correct. My body is in a storage unit and it is difficult to get to use it as a guide. If anyone can give me heights and distances from wheels and floor would be a great help. I will make the final adjustment when I fit the body.
Thank you
Rand
