Tracy,
This is our chance to find out if a 31" to 32" long exhaust
really will increase power.  The only downside that I see is
that the muffler might still be in the cowl (almost right under
your feet) so you might loose some of the benefits of cooler
under-cowl temps.

How loud was the tempoary system?

Ken, please refresh my memory on tuned exhaust systems. Optimum length
from port to Y-joint and then length thereafter (if it matters).
