a diy build mani would not come cheap, if you count up the bends in a custom set of mani's which have 24" primaries (and you are talking about 30" here!!!) on a kv6, and multiply that number by £15, which is the typical cost for a mandrel bent piece of steel, perhaps more for stainless??? you will easily exceed the cost of the janspeeds, this is before you've had the header plates laser cut and attempted welding it together!!!
To add to this, you will be ordering bends which are not off the shelf - as in, not a 15, 30, 45 degree bend etc.
