OK, I'm dumb, need help

Greetings again AJ! My mind is a little (actually a lot) slow right now, I take it BOV is blow off valve for the turbo? It surprises me no one has made a muffler for those yet, but the import crowd generally likes to annoy people so the majority of the market wouldn’t buy one anyway. I guess if you can’t go fast for a whole summer without breaking something, or your car slows down 2-1/2 seconds because you take your girlfriend down the strip (seen it in person, Honda Power!) you have to make up for it somehow...
