does anyone know what the diameter of the front y-pipe where it bolts to the manifold?? i got my rango a few months ago and not too long after there started to be an exhaust leak, then it started getting worse and worse....so when i looked at it the flange bolts were rusted off and stuck in the manifold end...the flanges are also so rusted that they no longer hold the pipe and manifold together...so i am wanting to put new flanges on the y-pipe...so i need to know the size

 

if its factory its prob 2 inch no more than 2 1/4
