1st Generation Audi S4 exhaust manifold & more

Looks great Matt!

I should have you make me a exhaust mani so I can throw that DNP in the trash.

Got the downpipe and dumptube all done, mounted the intercooler as well. The downpipe is 4inch diameter .065wall 304 stainless steel. The rest of the exhaust will be 4inch diameter .065wall aluminum.

Here are a bunch of pics:

Intercooler mounted:

Downpipe all tacked up:

Downpipe all welded up:


Everything installed on the motor:




All that’s left, fabrication-wise is the intercooler piping, weld in the O2 bungs on downpipe, and finish the exhaust. Intercooler piping is next on the list, once thats done, motor comes out and off to the machine shop with that and the head.

:naab:

God damm :bigclap::bigclap:

Looks amazing matt :tup:

Looks great. Good work

wow :tup: cant wait to see this thing run!

Looks dope man, your def a hell of a fabricator.

put it into production!

Make me one for my 3b

Ok.

dawm those beads are thin. What are you using?

Oh and did you get the SS tubing from vibrant?

stainless tig’s are always thin.

Looks nice. My only concern is the WG being a 90 degree or less angle from the runners. Any concern of boost creep with that setup?

Where should it go?
Edit: I’m not worried about it, plus, I’m most likley not going to be pushing that 42R to it’s limits.

Man how did I miss this! Pics of entire car plz. Shits hot.

x2.

If you’re gonna run lower boost your wastegate needs to flow really well.

Fap.

20psi to start, probably take it up to 30-35psi after break in.

I don’t say this very often around here. GREAT WORK!!!
