Now that the Pauter rockers will be installed on my
syncro, i was wondering about mufflers that will allow
better flow without compromising low end power.  I will
try the K&N as well for the same reason, although i am
a little concerned about it's filtering vs. the stock
syncro set up with air box and cyclone trap.

Robert Lilley recommends the DynoMax Super Turbo
muffler.

Has anyone tried it?  Or any other mufflers that
increased flow and thus performance without being much
if any louder than stock?

Thanks for any info.  And what model DynoMax fits the
vanagon?
