So I have decided to go ahead and upgrade my headers on my vehicle. I have decided to go with BBK shorty headers. I have came across an issue of not being able to find the sizes I need for a new mid pipe and X pipe. Most I see are 3 inches but I remember when I purchased a set of flow master outlaws they needed to be 2.5 inches. If someone could just help point me in the right direction that would be great.
