For the downpipe - I would suggest offering a standard 2-bolt flange, with an extra weld-on flange. Trying to mate a 2.5" downpipe to a stock exhaust (1.75" at best) is not ideal. I do think plug'n'play is good but not really beneficial in this case
I'd be down for the downpipe. Does your quote include replacing the stock cast dump pipe, and if so, will the new downpipe interfere with the A/C system? Real estate is very tight between the two down there.
I can provide some photos of a CorkSport downpipe with the divorced wastegate dump, if that will help. It bolted directly to the turbo and replaced the cast dump quite nicely
Yeah, we can include a flange. It is built to spec, after all. Normally, I can't assume that even half of this market can, or are willing to, weld it on themselves, hence the plug and play aspect. I can, however, assume that anyone that would want one has already enlarged the rest of the exhaust, and simply wants a downpipe to match. It would end in roughly that same location as our spring flanges.
As far as design goes, I've seen that pipe, and I like it. The problem is finding those outlet flanges is damn near impossible, and they aren't readily available when I do. To create a one-piece downpipe like that would require more material, including tubing, which puts it up to $270-ish for something like that, and It would not be stainless. Not that anybody drives their Capri in the winter, anyway, but if I didn't say it...
I'll design it so it doesn't hit the compressor, so no worries there.
The bend over the rear subframe is a crazy complicated one
Yeah, it wasn't that fun, but I did it.

I would LOVE a set of 4-2-1 headers for normally aspirated models. if not, a 4 to 1 would be fine.
