Lynn, you may have the small idea for a round spintech in your Borla.  I had the thought after looking at the cone in Jegs hot rod catalog.  Has anyone tried one of these cones, the smallest one is 3" in diameter and is $69.  If it would stand the hammering it could be mounted in a 6 or 7" piece of stainless pipe and should not be weight restrictive.  JohnD

I welcome any and all comments and criticism, as I stated, I don't have a clue how this will work.  JohnD
 
I think this will be rejected out of hand. Just enough flow to get off idle but no more.  So now we have a 4" Borla stainless.
 
For the lower RPM the smaller core diameter would be OK. But the least amount of restriction possible is far better.
 
The Spintech worked. It just had a bad shape. How about a round Spintech?
