Precisely! I used an OBX generic resonator (like they all are), from ebay, and just bought fender washers (2.5" diameter), in which the hole was only a centimeter around. It was simply welded shut and polished a bit to make it look cleaner.

Like m3an said, i modeled it after AA, but a standard pipe would work. I just wanted to make it look cooler, is all.
