Searching on this has confused me more than it should have. I'm going to be purchasing a Cobb CBE and an Indivia DP. I see the Cobb TBE comes with a Bellmouth DP, but reading about Divorced VS Bellmouth has me confused. Should I purchase a Bellmouth or Divorced DP? Will I see boost creep with the Bellmouth version Invidia DP? EDIT: After more reading, I'm going Bellmouth.
As far as boost creep, I'm not sure. I've seen a bit more low-end torque with the divorced, however bellmouth is much cheaper.
Some bellmouth downpipes give you the best of both worlds. The large cross-sectional area of a bellmouth for excellent flow, with a cast-in separator to keep the flow paths separate where it is crucial.
i love the whistle sound of my divorced.* *That's only in the mornin. You supposed to be up cookin breakfast. WOoo WOOO!
the Divorce is better, however both work fine. You don't have to worry about the wastegate air interrupting the turbine flow. However, it's not much interruption anyways because the hot gasses from the wastegate don't flow towards the turbine wheel....
This is the correct answer. For the small time stuff that we are doing, it doesn't matter to much. To try and eeeek out every last little bit of power, the divorced is the way to go. Russ
Once again, I'm glad I asked. The extra $$ doesn't bother me too much. I've been budgeting for this since spring. I will keep reading about it though. Thanks.

If I were to run a stock-type downpipe, I personally like the APS unit the best. Cast iron divorced bellmouth ftw. Too bad you have to buy the whole turboback to get it.
