How to make your own Turbo back downpipe

[Keeper of The Kitten]

Jas11n,

Just thinking when looking at the downpipe in the pictures, is that a straight pipe at the exducer opening out to the larger bore later on? I understood that a 12° cone from the exducer to the larger bore was the best way to go, as per Marco's pipe? Would that be available on any new downpipes that are manufactured? I am going to need a Ø3" downpipe in the very near future and could certainly be interested if the price is right!

Been extremely busy this week (Damn japs - never happy ) BUT, I did manage to drop off Bry's downpipe and also put forward your questions and suggestions.
Speaking with Bry and Jamo last Sunday and agreed that getting to complicated will only push the price up (exhaust maker Stuart agrees too )
So, a cone will be used to increase the diameter from that of the turbo fange to the required 76mm/3".
A standard wastegate flange and pipe will be designed into the downpipe and unless stated otherwise will be welded in place. You specify if you don't want that, which will mean he supplies the flange and pipe should you need in later on.
The downpipe will end in the same way as Marco ended his, leaving you to decide what you do from then on.
He's a busy man, and doesn't want to have umteen different downpipes and you all would prefer it to be a good price.....agreed?
Speaking to him tomorrow, so will update then.

Any updates on this?

Am back on the case with this ASAP as Bry will prolly want his downpipe back soon . Jamo and Bry know why it's taken me a while, ie I've been in "scarey s**t" land for a month or so.

Still very interested, if this can be done this month as I'll need a downpipe for July
