The system you purchased does not have the NPP valves for the actuators that arpad_m stated above.
See the NPP valves on this one below link? (the valves on the below are on the one exhaust with the welded plate on it)

on a side note... with that $$ I put headers and a tune on mine... it is crazy loud. (The stock suitcase on the 2SS is good for 1000whp anyways). But normally when you tune the car, you will void the powertrain warranty if the dealership can verify the tune or mod was part of any problem that you have. Every dealership is different in that aspect. Putting on an aftermarket exhaust should not void your warranty, but a call to your local dealer should verify that. Good luck on the install!
