My guess would be that these cars have a by pass-valve and not a so called dump-valve. I would also guess that it wouldn't be very wise to install a dump valve on these because it most probably would mess with the ecu's info on intaken air mass and make the car not work properly.

no need for a blow off valve, surprisingly this car comes with one which is already very noisy.
similar to aftermarket blow off valves.
put Sport mode and rev the car (lets say 2nd gear), release the pedal when on 4-5k rpms and you will hear it.

Very addictive, yes, especially in Sport (probably because it spools up quicker with the increased throttle sensitivity)!

For clarity to the OP, it's called a wastegate.
