Got it. Love it. 
But I got mine for ~$155 thru www.jegs.com But mine's the 2 1/2" pipe. So that may be why it was cheaper.
It's gotta a nice deep rumble to it at idle. And louder when you tromp on it.
I don't have a sound clip, but if you go to their web site and listen to the clips they have, check out the 5.3L Chevy P/U. It's the closest size the the 305/350 that they have on there.
They have sound clips of the LS1 also, but those sound awsome stock.

I just got my dynomax cat-back a few days ago. I ordered the 3" version. You can't the whole thing but you can order the individual pipes (p/n 43248 and 44063). I opted for the welded ultraflow muffler p/n 17227(flows a ton and doesn't sound too bad), so that brought the total cost of the cat-back up to about $230.
