A.) Dump valve on that engine is a stupid idea and will play havok with all the readings on the multiple sensors that engine has. It comes out the factory with a Re-circ dump valve.
B.) It won't do anything anyway.
Due to it being a Re-circ dump valve if you fit a induction kit you should hear it alot more. Only one you can buy off the shelf that fits properly and gives a performance gain is the GSR kit.
