Are dynomax super turbo mufflers worth the cost?

Looking to quiet down my ride. It's currently a 350ci 340, 10.5:1 compression, p&p j heads, 4 speed, hooker super comps, 3 inch exhaust, x pipe, 2 chamber mufflers, to full tail pipes out the back. I'm thinking of using the large case 3" super turbo's to quiet it down alot. Only thing is that they are 200 for the pair. I've listened to a few videos with mopars and those muffs and they didn't sound so great. any other recommendations for a pair of mufflers? Here's what it sounds like now (yea its a b-body, but the b body forum kinda sucks).
