FAIL, those pics are from vwsport.com, so it's a VAG 5cyl product

the burns collectors are deininitely nice but with a pricetag of $300 and up, I'd rather spend a week replicating one. that's for 16ga material, too. IIRC they don't deal with sch10/40.

heres my contributon to collector making. cut four equal lenght sections out of straight pipe. 4" lenghts are regularly used, but 3" and 5" are common too. the longer the better the flow, but the harder the manifold design for packaging reasons. find an angle that works for the lenght of pipe (between 10-20 degrees). you want to end up with around 1/4 of the original circumference on the end of each pipe after making both cuts to make a 4-1 collector with the discharge circumference equal to a single uncut pipe. hope that makes sense. the first cut is easy. for the second cut, you need to find a way to turn the pipe 90 degrees on its axis, and make the second cut. this is cruicial as the fitment depends on it. one degree will create a gap.

all four cut and ready to be cleaned and weld:

Right, that's my thought too. They only deal with their thin wall stuff, and fancy alloys in their turbo manifolds.

Nice photos and writeup. Looks like those were cut on a band saw?

We have a Mazak FabriGear (6-axis laser tube cutter) at work. I was actually thinking of cutting some intake and exhaust bits on it (if I ever actually ended up getting a turbo, that is).

Does the inside get welded, also? If so, I can put in a back-bevel to create a weld gap on all the acute-angle joins.

With a machine like that, you could easily put people like me out of business (well, out of my hobby)

yeah, bandsaw. they can be cut on a chop saw too, but it takes more trial and error due to the blades deflection.

bone you have pm

Wouldn't worry too much about it, Tim Actually it may not even be able to do such acute cuts, depending on angle and wall thickness (shows you how much thought I've really given it).

Sprayed, got your pm.

There are no words to describe this manifold. It looks pretty and well-designed, but close up... good god.

The wastegate tube is less a mode of exhaust gas transportation, and more a piece of art:

Thanks Andrew and Tim, now my girlfriend is ******* pissed. Mostly because she doesn't understand why I was completely distracted from what she was saying to me while speaking out loud about how I'm ready to jizz in my pants over an inanimate SS turbo setup.
