Hushpower cone mufflers. Whose used and recorded video of the sound?
 

I can't be the only one who has thought of putting a hushpower exhaust on the 4.3. Ive read it's meant for v6 engines, and suppose to be relatively deep sounding and quiet. I know there are other versions of the cone style muffler. Everyone chime in. I've had a Magnaflow Glasspack in place of a Resonator on a 3.8l s2 n/a 98 Gp, then replaced it with a ZZP 3 Chamber rezzy (which was quieter)
I liked how the Magnaflow sounded at idle but not sure how it will sound on the 4.3
