Top mount manifold

[stevejames3]

hey i searched and i couldnt find anything specific for this topic. my question is, what exactly do you have to do to your exauhst when you hook up a top mount manifold. is there a "test pipe" to extend the o2 housing or dp? any help would be great. i just want to find out how to make it all work efore i buy one. also anyone have any good (or bad) experiences with ssautochrome or any other companies please let me know. thanks

You need the downpipe extension, I'd just run it to the pre-existing downpipe.

Flange is the triangular 3 bolt flange, and the turbo exhaust flange is whatever your turbo uses.

No one is going to have an off the shelf extension like that.

Build your own.
