FEEL's is an oldschool high quality JDM company.

^some current exhausts they have.
their parts are very rare in the US here though.
I know of one person with a FEEL's header, but nobody
with the exhuast yet.
you might be the first to put it on a CL9 in the states
that I know of if you go for it.
I have Mugen in favor of FEEL's on my list simply becuase
I know what the Mugen will sound like, where as I have
no idea about the sound of the FEEL's. But I have several
other parts from FEEL's on their way, and I can tell you their
reputation for quality is solid.
