Exhaust flare tool?

[Roa, Greg]

Ok, my Audi question of the day:

Does anyone know of a inexpensive tool or a procedure to make the flares for Audi exhaust pipes?  I'm talking about the flares that are on the joining sections (ex-between the middle and rear muffler sections) that use the metal donuts in-between them.  I need to replace the exhaust on one of my 4kq's soon, and I'd like to fab it myself, but I'm not sure how to do the flaring.

Also, is there a good source for the three point flanges?

Thanks!
