Downpipe tech... FM Turbine outlet vs 3" elbow vs BEGI Separated
#24
The FM stuff is expensive, but it fits well and ships with minimal delays.

Here is the plan:
FM elbow with standard four bolt flange replaced with v-band! (IF we can get the v-band to reliably weld to the turbine elbow***)
Custom v-band downpipe to v-band mid pipe to v-band muffler...
All 3 inch.
*** my fabricator feels he will be able to do this reliably but wants to see the elbow first before committing. Worse comes to worse we need to fabricate the flange for the downpipe side.

Or, perhaps this will work?

What you want is something like GSP T25 T28 GT25 GT28 5 Bolt to 3" V Band Turbo Outlet Downpipe Flange Adapter | eBay
That's actually in my cards if I decide to upgrade my mani/downpipe and go with a EWG.
P.S. Abe built me an entire exhaust, with resonator, and downpipe for a little bit more, including shipping, then what you are talking about spending on a couple pieces. Stop trying to be cheap, you are costing yourself money.

I figured all 2.5"/4-bolt flanges were the same, but the FM version did not match up with a paper gasket I directly compared it to over at Silicone Intakes prior to installation (so far off I didn't buy the gasket). Just sayin' it might need some tweaking to make it fit.

My thinking is that I would be surprised if FM decided to reinvent the wheel in regards to flanges. Every part that is unique to thier part is another that they have to have a special supply chain for.
Blaen, the reason The FM piece is attractive to me over the 3" grand directly on the back of the turbo is that the tight bend is already done. With the current DP there is less than 3/8" clearance between the DP and the tray. If I upgraded to a different manifold that changed the position of the turbine exit I think your idea is perfect.
My fabricator told me that a good amount of labor time would have gone into making that elbow and he estimate that in materials and cost it would equal out to be about the same cost.
The FM part is on order and when it arrives I will be doing some measurements and see hat works best.

If I had ordered my full exhaust from Abe with no resonator, I think it would have been something like $950 shipped.
You are talking about $770 for just an elbow and maybe a downpipe. Plus what your fabricator charges you.
How in the world does this make financial sense for you? Abe already knows and does all of that on everything he builds with what you are talking about.
I mean, do what you want man, but you seem to be spending more on something for at best no gain, at worst worse - for more money! If you want what I have dyno proven, copying me would be less money instead of going into uncharted territory that has no mentionable benefit I can see.

There is an unfortunate amount of bends in the exhaust path but that isn't until you get to the muffler. I have that big honking magnaflow mounting in the factory position and the exhaust routes around the differential/axles the same way the stock one does. The bends are nice and wide though.
