Im made my own for my Iron Head Bobber a few years ago,
Took me about 2 hours and $100.00 of bends , I tyred Wraping them but wasn't happy so I then got them Cermaic Coated.

If you do decide to go ahead with making your own and you dont have a tig, just tak them togeather with a mig them take them to a shop to get tig welded as you don't want to have welds looking like "coff" cocky shit ^ .
Bends can be found alot cheaper, just call a few exhaust places or even try proex mate.
