Kelly,

The really nice thing about the slotted tube is that anyone with a side
grinder and a hammer could build it.  I cut the outer tube with a chop saw.
Used a side grinder & die grinder for shaping the inlets, etc.  I purchased
all of the materials off ebay.  The muffler shop expanded some of the misc
pieces used for the joints.  So, this is a project that almost anyone
could accomplish with basic tools (welding excluded).  The difficult part
(for me) was deciding on the design.

Mark

P.S.  Thanks for the compliment.  ;-)
