which mufflers

I'm looking for a muffer recommendation, probably mainly from the GenIII guys since they have a little bit different sound than the sbc.

Anyway, I don't want the loud metalic sound that 40 series flowmasters have. I had those on my 72 GMC, and I guess I'm over that.

What I will be running is long tube headers, 3" pipe with and X - pipe in it, and turn downs in front of the axle. I want something that is free flowing, with a low deep rumble, but not overly loud. I know loud is very subjective, but what better way can I explain it. I was at the track the other day and a friend with a LS1 Camaro with true duals said his exhaust with Moroso Spiralflow (or something like that) wasn't too loud.....it was WAY louder than I want.

I was kinda thinking about Hooker Aerochambers. I had a Hooker catback on my LS1 formula that sounded good, but that is a crossflow muffler (1 in, 2 outs) so it's not representative of what I'll have on my truck. I have Magnaflow Magnapacks (essentially glasspacks w/ stainless steel packing) w/ x-pipeon my corvette and it is also way too loud for what I want.

I know Magnaflow makes a kit for our trucks, but I really don't feel the need to pay the extra money for stainless steel, cause I'm still going to use some Flowmaster Ball-Flange collectors (no leaks). Also, since I want it to dump in front of the axle, it will be tucked up in the frame rail, and it's connecting to LS1 headers (angles and widths are different) I don't think it will work real well. I figure I'll have the pipes bent up by an exhaust shop, but still need to know what mufflers.

So let's hear some suggestions. If you have sound clips that would be great.
