Best sounding muffler for 2004 5.3.

Space. Or if you run 2 the offset might make them fit better

Does it sound like the one in the video provided in this thread?

It sounds pretty similar.

I have a 12579 coming. Should be here by Friday. Going to bolt it on with some exhaust clamps and be done with it. I'm not going to worry about putting the resonator on it.

im a big fan of flowmaster, and as far as the 50 series goes, its a little louder than a magnaflow, and no where near as loud as the 40 series. I really liked my 50 series so much that i put it on my 04, 08 and my 11. i did however want it louder after a year and swapped to a 40 series on my 04(lots of drone). on my 08 i swapped from the 50 to a super 44(even more drone). Then finally on my 2011 i swapped the 50 series for a 40 series delta flow. IMO its FM's best sounding (outside) and very little drone inside.

Somewhere in there on my 08 i put a short magnaflow on with the stock piping, and i wouldnt do that again as it droned worse than any FM. thats not to say that i wouldnt put on a longer magnaflow someday if the noise gets to me.
