which muffler for a 4.3L silverado

i'm about to buy a muffler for my truck but im not sure which one....what do you guys think sounds the best on this truck?

depends what year my 92 had a JONES (flowmaster ripoff) with no cat, and everyone thought i had a small block. sounded sick.

i say a flowmaster 40 series dumped. I had one on my 4.3 sound good cause it was bagged and right on the ground. My buddy has a newer 4.3 and has a flow dumped and it sound great. Oh ya ours are both standards too.

flowmaster or gibson......my mustang and my dually both have flowmasters and sound awesome.
