reading this thread got me thinking: http://www.theminifo...-for-the-15-su/
the med kits look nice, but I don't like the flat cut off surface on the HIF44 stub stack they sell. I have read what wizard has to say about flow potential of different shapes of ram pipes and stacks.
currently I use this one which does not have a great fit and is to soft in its base:

but have also often looked at this one because it fits inside a k and n filter, but it looks like it will require a bit of sanding and shaping:

what ram pipe or stub stacks do people use on HIF44's?
are there any longer ones?
