You can never have a flange that is too thick...stud is too short in this case.

So the flange is slightly less than 1" thick. I attached another pic from another perspective.

The inventory checklist shows DP studs as 30mm x 1.25 x 8 which is what I received and is pictured in the photo.

The flange isn't flat either. It rocks back and forth on a glass slab and turbine. Looks like it must not have been machined down.

So is 1" too thick?

who's it from....in most cases, .5" flanges are used. if it's not flat, it will obvious need to be milled. belt-sander could be your friend.

Usually you start with .5" and then mill after the part is done for flatness. 1" thick is pretty outrageous. it really only needs to be like 3/8" in finished form.

Thats the begi S pipe guys, if its not that thick the wastegate flapper doesnt have enough room to open.

When I got that pipe I had to go hunt for larger studs. I think I wound up using 45mm ones and The bolts dont even thread on completely.

Yea, I had quite an excursion with their pipes. First one hit the coolant line, hit the transmission and the lowerbolt wouldnt thread on because it was to close to the pipe. The second one worked.

They charge out the *** for that.

If he cant find studs he's better of using grade 10 bolts.

Just grind it down flat, who cares how thick it is, and go to local parts store and get some real bolts that will fit. End of story!

No no.

The pipe is not the problem, thats the normal flange that comes with the Begi S. The pipe does not come with studs, the turbo you have comes with studs but they are too short for their enlarged flange. If you want longer studs to work with that pipe they charge for em.

Btw, the begi S pipes flange design is identical to the downpipe on a WRX. Found out by accident, was surprised.

My BEGI downpipe had no hardware when I got it, it was supposed to. Stephanie sent it out after I informed them they were missing. I sourced my turbo elsewhere.

As far as I know they include hardware with the DP and the manifold.

For the Divorced DP this is what BEGI says:
The two piece downpipe comes with turbine outlet mounting hardware, cross bolt, and O2 sensor bung plug.
and the BEGI S
The two piece downpipe comes with turbine outlet mounting hardware and cross bolt fastener.
So ya, if they say it should come with the hardware it should. And it should fit. The OP has a valid complaint.
