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.  ;-)

Bill, 

Here is a shot of the exhaust side of the engine without the heat shield.  All fits together very nicely.

Bill, 

Here is a picture of the inner pipe of my tangential muffler.  Material is 625 Inconel.  If I were to do it over I think I would angle the slots at about 45* so they would scoop the exhaust gases as it swirls around inside the larger tube.
