Mazda 6 MPS BOV (stock Bypas tuned to Blow off)

Here is a simple (but not the safest) way to enhance your MPS sound: 1) "Ease" (by pushing the two brackets together) the ring clamp and move it 1-2 cm (half inch) down the hose which is connecting the Bypass valve to the intake manifold. 2) Detach the hose connecting the Bypass valve to intake manifold from the valve. 3) Take a cap from a plastic bottle (from cola etc.) and gently push it into the end of the hose u just detached from the valve to isolate the manifold from the environment. 4) You&done! Rev above 3000 and lift your foot quickly from gas to make the "whooosh!" You may lose ur warrantu doing this, and the engine may be unstable on idle. And you may also experience choppy performance while shifting (the quicker the shift - the less choppy it becomes) Have fun!
