The car holds boost so much better now. The sound of this BOV is (at least at moderate boost levels) very subtle, and pleasing to the ear. I can't imagine anyone being bothered by it.

Appearance is top notch, improves under-hood view more than expected, especially without the return hose to the stock intake. Build quality seems to be first rate.

After replacing 2 stock diverter valves, I feel foolish for not doing this years ago! :)
