Okay I dont wanna seem like a dick but yes, my header is "split" as you call it. Like stated I have a JDM Version 8 Twin Scroll set-up. Stock "split" uppipe, header, into the turbo. Now Im building a "split" aka Twin Scroll uppipe that bolts onto the stock JDM Version 8 header and will be long than stock(same piping size... 1.75" each tube) into a T4 divided flange.

works good, but is 304.

Add Bracing, Cuz when i use t4 split flanges, there on bigger frame turbos, and they weigh 40lb+ (GT4294r's GARRETT, not obx, jdm style ****)

Its not cheap to be cool!!
