Custom downpipe

[canadiandiesel]

Did my search and now I'm completely lost or my comp d fu is crap.

Got the s400 series turbo installed with a steed straight t6 manifold. However looking for a proper downpipe, I'm thinking I need to build one?

From my understanding the exhaust flange is a full marmon? How tight can one do a 90*

Thank you for any help.

If it is a full 5" marmon I used a cast 90* full marmon elbow on my 2nd gen to squeeze my downpipe in.

I had to build my own. Was a pain but got it in there. Isn't the prettiest either, but it works LOL

I made my own adapter from 5" to 4". I cut the 5" exhaust flange really short then welded the adapter to it then used a tight radius bend 4" exhaust.

I used it as a normal downpipe before the hood stack, just make sure theres enough clearance between the ac line.
