the waistgate is a swing valve inside the turbo that is held shut untill boost is achived. then it opens as needed to let the extra exhaust gasses bypass the turbo to maintain the set psi.. The bov vents the pressure inside the intake manifold when you let off the gas or shift,

research the exhaust, a cat back system probably wont be to loud.. for better performance, id get a downpipe, but thats just me..

The sound from your exhaust is based FAR more on the muffler you use then the size of pipe. If you use a ricer little coffee can it will be loud and buzzy but if you buy a good full size muffler you will love the sound.
