Les, you are not alone.....
I've only had the chance to drive my newly completed Midget on the freeway
twice since getting it registered two weeks ago, but the one thing that I did
notice, and actually commented to a fellow Midget owner, was that the exhaust
noise did drop off significantly above 55 mph. A complete contrast to my old
Midget which just got louder with speed. I can't comment on the RPM's as the
tacho's dead.
This car has the factory standard 1275 cast iron manifold. The muffler is long
and thin, I can't tell you anything more about it.
I don't mind having a quieter car for the high speed freeway stretches anyway.
Cheers,
Eriks Skinkis
