Could anyone that has the stillen true dual installed or sitting in the box do me a favor. I need to know the pipe diameter at the center of the X crossover. I sure look's like it's 3". Could someone measure that point for me please. I need to buy a X pipe and I want to make sure I don't go with the wrong center pipe diameter on it. Here's a pic of the stillen X pipe and a arrow pointing to the point that I need the diameter of. Please excuse my crude coloring out of the rest of the system that was pictured.



Thanks to anyone than can help me.
