Installed skunk2 alpha headers

I installed skunk2 alpha headers and everytime I drive I hear a grinding noise. I have my rear mount upgraded to the 70a. I check and it's not hitting anything. What can it be?

Following, doing mine soon. I bought a used Alpha header last year and finally got the full race exhaust to pair it with. Is there any extra hardware I'm gonna have to get since I got my alpha used with no hardware?
O2 extension, the hanger, new donut gasket and exhaust manifold gasket
Thanks man! Since the alpha header is 2.5in collector, do I need an adapter for it to mate up to the full race 3in?
