So both of you want to remove your resonator assemblies from your civic, 
huh?  OK, here's a step by step way to do this.

you will need: 

a 10mm socket wrench with a 4-6 in extension
Phillips head screwdriver

1. Remove your front bumper cover.

This is done by removing the 5 (7?) screws located on the front 
cover where the front lip of the hood meets the cover and removing
the 2 screws located in the wheel well area which can be accessed
by peeling the plastic splash guards from the wheel well area back
into the wheel area and usig a a long phillips head screwdriver 
to get at it from the bottom.  You will notice a cutout in the cover so 
that the screwdriver can reach it straight without having to unscrew at 
an angle.  There will be 2 more bolts locatd underneathe the car whic 
will then free the bumpercover completely.  Pull the cover forward and be 
careful not to scratch it by accidently dragging  it on the ground.

2. remove the resonator assembly.

If you now look at the area directly in front of the passenger 
side front wheel, you will see a large black plastic box and a plastic 
pipe (U shaped) coming out of it.  The large plastic box is hels in place 
by 3 10 mm bolts with rubber spacer/washers on it. simply unbolt these 
and pull apart the resonator boxes and tubes and take them out.  You will 
note that the opening to the airfilter box now draws air from this large 
empty area.. A great place to maybe create some ram-air type assembly.. :)

3. Put back on the bumper cover and tuck back in the splash guards.

Be sure to put the spash guards back in place, since this is what 
prevents your engine from drawing in water when driving through puddles 
and stuff.

Hope this helps..
All in all it should take you 30 - 45 minutes to do this.. maybe faster 
if you are good with tools.  Let me know how it goes.

Also, I found that the sound of the empty airbox seemed "boxy" and 
"hollow". If you can get some thin egg-crate foam and some spray 
adheasive, you can line the bottom part of the air box and reduce this 
boxy sound.  Be sure to glue it securely since you don't want the foam to 
be sucked up to the airfilter.  The correct method of using spray 
adhesive is to lightly coat the two surfaces, let both surfaces dry until 
both are tacky and put the two together.
