Integras have a double-walled "A" pipe from the exhaust manifold to the
cat,and a weld on the inner ppipe breaks and you get a buzz at ~3300 rpm.
I'm not sure if your CR-V has such a dbl.walled A pipe,though.
I've seen a procedure on the web where you cut two slots 1/4" apart with a
hacksaw through only the outer pipe,dimple in the inner piece to contact
the inner pipe,and braze the opening shut.I have not tried this myself yet.
My GSR has the buzz/rattle,the heat shields are removed except for the
manifold shield,and that has a hose clamp snugged down on it.

I wonder if the Honda people would know if the pipe is double walled, or if
there is a service bulletin on this?

Funny the buzz is only at 2300 rpm and in overdrive gear with the slight
load on the engine.What pisses me off is this is about the RPM that I drive
in most of the time

I supose people with dual exhaust on there V8's get used to the noise, I can
get used to the buzz,rattle,shutter,or what ever it is!
