twin scroll uppipe material?
I'll make it short. I have a custom waterjetted jdm twinscroll header flange coming my way to build a custom rotated uppipe that will bolt on to the jdm ts header and have a t4 ts flange on turbo side.
What are some tubing options for me? Material, o.d., I.d., thickness...? What's the most cost effective material and what would be the cream of the crop material??? Thanks

Inconel is the best. Then 321 ss is very good too

Well first, is your header split for twin scroll, cuz if its not, just run a t4 non split flange, whats the point, thats somewhat the reason for the turbo to be spilt, Second if it is 2 - 2-1/2" max 16ga 321 stainless for each run into the split works good, But if your not running a split header, then, if your uppipe is 2-1/2" get a transition to 3" reduce from vibrant
http://vibrantperformance.com/catalo...oducts_id=1078 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!! |

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.
