Headers: MAC shorties
Cats: ...No idea, but high flow
I installed the headers myself it wasn't difficult. I can tell ya where i got em if ya like.
Then i took everything else to "Hanksville Hotrods" and had those guys build the whole rest of the system. In case your wondering...yes...you should be jealous of this exhaust system, and to answer your next question...if you want the bends and pipes to duplicate the system let me know id be more then happy to get your in touch with Hank, its not a direct bolt "on" because of a lot of fitting and some welding but its close and it can be duplicated.
