Muffler choice?

[bryanw1968]

I've been running the 50 series 3 chamber flowmasters on the '68.
It sounds good but obviously has the "chambered" sound. A buddy of mine has a set of Dynomax bullets and it sounds great. It's not a full exhaust so it's really deep sounding.

I'm thinking of changing to a non-chambered style muffler. So far I'm considering dynomax ultrflow, the dynomax race bullet, magnaflow race and maybe even flowtech. Does anyone have any experience with any of these?
I want to have a deep tone at idle and a raspy sound at WOT. I DON'T want it to sound like a pair of glass packs. Nothing wrong with glass packs, I just don't want them on this particular truck.

Thanks,
B
