Are you on 93 Octane?

Mark, won't the stock cats burn up and need to be replaced after a certain period of time? Also, isn't there potential for the stock cat debris/burnt material to get back into the engine?

How much power is lost from going to test pipes? I'm currently using test pipes. My power/tq is listed in my sig.
