the extra chamber is for further silencing of the engine, I bet there is no real difference in performance between the 2 types as the most restrictive part of the tuned pipe is the stinger. I run an rb pipe with no additional silencing just the tuned pipe body and it is loud, very loud!! although it does gives my motor great rpm for a .23 motor, it absolutely screams.
