Exhaust Manifold
-Turbular
-Matterial
-Flange
-Cast
Stainless steel, Inconel, Mild, etc.
T25, T3, T4 etc..
When choosing a turbo exhaust manifold,take into consideration flange size (T3, T4 etc..)
Another option is either an internal wastegate or an external wategate, which will require a flange to be on the manifold
Turbocharger
-T25
-T3
-T4
-Ball bearing
-Conventional Sleeve
-Standard (Oil) cooled
-Water cooled
-IHI
-Mitsubishi
-KKK
-Trim Size
-Wheel size
-Exhaust Flange
-3, 4, 5 Bolt or V-band
There are several different aspects of a turbocharger itself. Depending on the goal of the turbocharger, these options are a vital part to ur system. Deciding the correct trim sizes and flange sizes are a task of their own.
Wastegate
-Internal
-External
-SIze..35,28,44,45,60mm...etc....
when using an external wastegate, a flange must be placed on the exhaust manifold.

Another consideration with a downpipe besides diameter and glanfes are the addition of a flex-pipe. a flexpipe will help to reduce stress on the xhaust systems and xhaust manifold by allowing movement.
