		I just ordered some goodies for my new sidepipes: 
 
Dynomax 23.5" long X 3"ID X 4"OD Bullets 
Car Chemistry 3 disc inserts for the 3.5 OD collector, to go just in front of the Dynomax Bullets 
Hooker Weld-on collector 2.125 inlets and 3.5 OD outlet 
 
It will be a while before I run this setup, since I just lunched my motor and will need to build a new 540 BBC for the Cobra before I can hear how loud the new pipes are. 
 
My theory is to use the inserts to bounce the sound around and the bullets to absorb some of the sound.  I suspect the two methods each work best at different frequencies, so I hope to have a reasonable sound level at the exit.  If the CC inserts are too restrictive, I can remove them since I will have a collector flange bolt joint.
