I purchased one from Tommy. No regrets, although I haven't recceived & installed it yet. My biggest question is the noise. If you're saying it's louder than a relatively loud exhaust system, then I'm not sure it's for me.
Don't get me wrong, I want the performance and turbo longevity benefits of dumping excess pressure from the intake...but is there anything else available on the market that can do this without all the noise. I know escaping air under pressure will always make some noise, but it wouldn't seem to be too difficult to increase the outlet area to decrease gas velocity, and reduce "hiss".
Any thoughts? Has anyone seen other options that would do the same job more stealthily?

The stock surge valve actually does all of the work. The Mopar BOV isn't really the valve, but a vent that dumps into the engine bay instead of back into the turbo inlet. Just a noise-maker, no performance advantage over the stock system.
