 If this restrictive termination of the 2 inch diameter exhaust pipes
 did not harm performance, than I believe a 3" tangential muffler
 without any restriction might perform very well.

Those were too simple. They must be beefed up. You cannot merely
squish the end of the pipe and call it a true fish tail muffler :-)

I'm not planning on using a fish tail, but knowing its effect on
performance would be very useful.   Jerry
