Hey everyone, I have a 2006 Mountaineer v8 and I want to build a custom exhaust system. I am at school right now but want to start designing the system now, and need to know the pipe size. I believe it might be a 2.5 inch but can someone clarify? Also any suggestions on what to do for best fuel efficiency and power would be great!
