So I did tweak the exhaust to see how the performance and sound may change on my 1935 LaSALLE.
For the sound, I leave it up to your judgement...

As for the performance, I got a noticeable improvement of low RPM torque as well as overall power..its like driving a new car.
The poor old flathead could not breathe with that huge muffler stuffed down the pipe..
sounds pretty darn good to me!
I may just do the same thing on my 47
