Gonna start getting ready for this summer now and first thing I am going to look at is a home brew version of a 3" straight through cherry bomb using stainless wool instead of the traditional glasspack.
there is only 1/4" between the inner core and outer body this is due to the heat shield I have being only just under 4" dia so everything has to be quite compact, you will see what I mean over the next few days
the raw materials
