Shiny new bits came to the door today.. BEGI S4
 

Hey guys,
I got a couple of boxes delivered today. I'll load up a few pics when get some more pictures, but here's a couple of starter pics of the newer S4 manifold the BEGI is making now. No more stainless.

I still have to inventory everything, but I'll upload more pics once I get it all sorted out.

ooh pretty

Interesting. Compared to previous s4 it looks like it uses larger diameter tubing, unequal length runners and the turbo flange sits a bit lower. The merge from 2 and 3 looks less effective than before. I suppose the main benefit will be increased durability?

More churbulence for spool im guessing.

Make sure to get the flanges surfaced since they are now coated.

Here's a measurement. I too thought the runners were going to be more equal than they are. The older version of the manifold, the runners looked longer and close to equal length. This is a very well build unit, I'm sure almost indestructible.

One note: BEGI didn't put the EGR bung on the manifold, but I have talked with them and it will be resolved. (very good customer service)

What do you mean "In before fitment issues"?

Here is an update:
I got the manifold back the other day from BEGI. They did a great job and it was a quick turn around time. The surfaces have been machined and the EGR bung added and everything recoated. The install starts this weekend.

shiny will go away by July.

I understand that. Just a description based on it looks like now. So and the fun begins.
