Default Anyone Using Glasspacks?

My '72 is great, but the exhaust is too damn quiet. I got a mildly built 350 with long tube hooker headers, 2 1/4" exhaust with an H pipe and flowmasters. The only time I really hear the exhaust is either idling on the driveway, or with the rear window out when cruising and then just barely. So I went ahead and ordered a pair of 15" 2 1/4" glasspacks from JC Whitney. If I don't like'm, I can always weld the flowmasters back on. I have glasspacks through headers on my '68 chevy van and I think they sound awesome. Has anyone out there pout a set on his or her C3?

i'm running a 3.5" round, 13" long glasspack on my sidepipes, and they are turned backwards, so the baffles are in a downflow with the exhaust...loud, deep, pretty much a race car sound...not the flowmaster rumble which everyone here has.

Got glasspacks on my sidepipes. Quiets them enough but not toooo much. Basically keeps the sound legal.
