Bobby,
I believe it does not make any difference to the
exhaust performance how many pipes are coming out of the muffler as long as the
total area of all pipes remains the same. As soon as you make the pipes (tail
pipe) larger, you will get more noise. All sporty sounding exhausts are based on
this.
In some smaller cars it may give better ground
clearance having two small pipes instead of one big one.

Richard,
Driving down the road observing mufflers. (got to get a
life) I have noticed some cars with two small pipe exiting the muffler. I
wonder what effect this would have on sound and rpm's verses one small pipe or
one large pipe?

I'm not all that familiar with rotary characteristics. Puzzled why
tail pipe is such large diameter (2 pipes seam welded together). I would
think that exhaust pulse at any one moment is no greater than a single
tube diameter. Maybe someone can explain to me.

Al,
It seems you are right with
the pipe sizes. We did a test at the last Shady Bend meet. A small
resonator box from Monty and added a 1 1/2" exit pipe. The
result(regarding noise), also subjective, was amazing, and the engine
lost only 200RPM at the top end.
