I called Paul today to order my muffler, and ended up having quite a good chat with him! He said he was going to give Gary a call, to ask if he had installed his muffler and if there as any drone issues like the magnaflows. I suggested he check the forum for Gary's install pics. He says he has only 16 left and msrp is $335, so $201.53 is not a bad deal. Also he said these are made in Italy. Website states they are stainless internally with an aluminized shell.
