Exhaust flanges and shorty headers are perfectly built

The platform I am build works perfectly with and I'm sure they have many more different flanges for different applications

In case anyone was wondering the 3 bolt ****** is in fact the same one used on the shorty header and has a 3 inch outlet. Fit and matched up perfectly.
