From my experience Ken is correct. My '69 had stock headpipes with
aftermarket mufflers until just before the VA Rally one year. Discovered
that one of the channels that the mounting bolt slid into was cracked,
so at the last minute decided to install a pair of nice used stock
"torpedo" mufflers and crossover. Low and mid-range power seems better
and the fuel mileage went up 4 mpg average. Had been getting 47mpg or so
on mostly highway, increased to 52mpg on one tank. The flat spot I had
at 3/4 throttle was greatly lessened too.
Now, were the aftermarket mufflers too restrictive? Is there really any
power increase due to the crossover? Don't have any data to back up my
experience, but the '72 project bike and the next one will both have
crossovers in the exhaust.
I thought Ron Komoroski did a nice job of putting a crossover in the
system and using aftermaket mufflers. This was on an Eldo he did (2 yrs.
ago or so, Ron?) for a customer. From what I remember he used an "H"
pipe at the end of the headpipes and then "turnout" style mufflers. This
put the mufflers pretty far back, but it looked perfect with the 'bags
on the bike. The sound was simply fantastic - I thought it should have
won the Best Sounding Bike award at the Moto-Fest! cheers,
