I've been looking for awhile now for a good cheap downpipe I came across one from ATP 350 Brand new from them plus shipping from canada big plus is you don't have to worry about a midpipe its a full o2 dump downpipe plus midpipe all in one piece

Its so much easier to weld together pipes than to cast. Obviously little shops are going to weld pipes together than to go with a cast design. I knew there is a reason why i didnt go with a subaru . I should have kept my ets downpipe to show that ams makes more power than any other downpipe. Just think about the design man. Its not complicated. The smaller the pipe, the more back pressure. A huge bell mouth will have FAR less back pressure than two different tubes. Tubulence will not come into play in our case. Does your wife like your stubborn ignorance?

Turbulence is indeed a factor, as is the sudden expansion of gas into the bellmouth and then contraction into the o2 housing outlet slows down flow. Keeping the diameter uniform is better. That, combined with separating exducer and wastegate flow makes a well-designed divorced outlet better than a bellmouth.
However, as you said, it comes down to cost.

Regarding my wife, she is able to understand theories when explained to her...but she does have a bellmouth downpipe on her WRX I'd suggest you keep the personal shots out of this discussion though.
