type 4 exhaust parts

[jasonscool]

I am having a hard time finding pieces to fab up my own exhaust. I can only find a handful of exhausts to buy premade and they are pretty damn expensive. I saw a post that was yrs old by Raby who said he is making an exhaust that would be under $300. Did that ever happen?
I am looking for the little pieces that bolt up to the heads. I saw some on that tangerine sight but they are like 250.
Is there any other options that are under 400?

I always cut em off old exhaust systems, they never rot up there. There are a few posts where guys have hammered thier own out but sllitting tube, but that is a lot of work.

I do not know if you have my manual but I show how to cut down stock heater box headers for use on a Upright conversion. That was before anyone sold parts. Then just use Bus for 914 muffler.

I just used an old set of heater boxes and cut the crap off for some ideas look here

1 5/8" stubs are ~trivial to make given a vise, bandsaw and a welder. (and some tubing)
("natural" size, if you will, the resulting oval after squishing the bandsaw cut is ~perfect size for the port)

Larger is far more difficult, as is smaller--- but a 1 5/8" stub transition to 1 3/4"or 1 7/8" should work just fine.
Hardest part is finding ALL the bits in one place.

MEGS exhaust warehouse (Cone engineering) sells most of the bits and has a few kits, including a turbo ACVW kit that may have most or all you need, and if you have a list, may be able to put something together for you.

Their SS bits are also sanely priced, but if you go SS consider slip fit+brazing or silicon bronze TIG, to ~eliminate cracking as SS is otherwise very prone to.

this is one of those super exciting things to me w/ my new tig, is finally doing SS exhaust right! I only just remembered I don't have an exhaust for my new bus, wish I had more time to fab one, although I may make the time yet.

Thanks for that link.

Here is the flicker photo album link of the exhuast Kengineering completed in 2005.
The pictures were taken prior to the exhuast being coated.

there,s some great photo,s in there of the exhaust.
did you make the stub pipes or buy them (little pipes from the heads).
if you made them how did you get them oval to mate the heads

[Stufenheck]

Bought 1 5/8" stub pipes from Aircooled.net. they came with 3 bolt flange.
Since then seen other styles for sale on the samba from other vendor.

I believe you can still buy the 1 5/8" Stub Pipes from George Narbel European Racing Headers: http://europeanracingheaders.com/products/914-4/ give him a call.

The Stub Pipes have the 2 bolt flanges.
