First off im running an AEM so yes I can use the VTA piece. My question is what kind of metal do I need? It asks if I want aluminum, stainless steel, or steel. I will be welding this piece to Buschur's UICP so will aluminum weld to that or do I need a different metal?

stainless steel for buschurs upic... dont make the same mistake the idiots who installed my upic pipe did, and that was welding a mild steel flange on a stainless steel pipe.. it looks like **** now.. and ive got to have the mild steel flange removed and a SS peice put on

Like Pure Player said get the stainless weld-on flange for the TiAL.

Dissimilar metals in contact will arc which will result in rust.


I guess I did learn something in high school .
