Default Open dump wastegates? Who's running them?

Done a lot of research on here and can't say that I've ever seen the topic arise. I've always ran open dump tubes on all of my turbo cars but it looks like most members route the wastegate into the downpipe. Guess I'm a fan of the jet engine sound the open dump produces when boost hits and the simplicity involved with running a straight pipe off the gate.

What's everyone's opinions? Pros and Cons welcome.

Thanks Shawn for the vids. I'm curious to hear what an open dump would sound like on a front mount setup with a full exhaust. I think I'll continue using open dumps when I build an lsx.

Damn skippy!!

Matt called me yesterday afternoon and told me he was done with everything but the pump. The pump came in yesterday and he was installing last night and ordering me some fittings which should be in today/tomarrow. I asked him if he thougtht we might get it on the rollers saturday and he sounded pretty sure, depends on parts.

Only bad news, Matt asked how attached I was to cruise control, which I don't drive it enough to use it, so I am loosing it. Scavenger pump is taking it's location!

4" mandrel dp with 4" magnaflow bullet dumped before the axle. Wastegate dumped to atmosphere. I hear no sound from the wg unless I am on the throttle and in boost. Then it's just the jet engine sound.
