[C320-list] Engine noise

[Stanley Rogacevicz]

Jon,
   Do it !! you'll be glad you did. I used the stuff from Defender (as
always cheaper than WM) 5 years ago that contains lead (I don't think WM
even had it) so my weight difference was significant but so was the
difference in sound. I had forgotten how loud the standard 320 was until
went on a friends 98 a couple years ago - wow ! what a racket!! I put
off adding the external handles until last spring and it was a big help
for gripping the rear. I just used simple white cabinet door handles
from a home goods type store for cheap.

Dick,
How much heavier does this make the two covers? I have been
procrastinating on this project for a couple of off seasons now. Perhaps
it's good time to also add the external handle that some have added to
the aft cover....

Regards,

Jon Vez
