I flew over the weekend my F22 and a friend of mine with the same X45 but on a Rafale and of course straight pipe, the Rafale was stronger that mine, it seems when it flies at full speed and when it takes off. Because of that i want to build another F22 but this time with straight pipe not bifurcated. Having 45 mm diameter of the tube from the site you gave it to me, i saw that having short axis 25 mm, maxim at F22 is 35 mm, so i supposed to let 5 mm for cooling, will have the long axis around 81 mm. I will ask a company if they could make me this pipe. Do you think is correct? The length as i calculated will be 240 mm, remaining 10 mm out of the plane.
