How to upgrade muffler???

I've been really really trying to figure out and decide this: what is the best muffler/system that will deliver the best deep V8 sound? Can anyone help me?

yes, larger bore and specially designed rear mufflers are around specifically to alter sound outputs ( mostly increasing volume) check out an exhaust specialist and magazines for custom and hot rod cars. these have many suppliers advertising and magazines often have a write in question and answer page. otherwise try petrol head site.

Magnaflow makes a nice sounding muffler. Their cat-back for a G6 is a little quiet, but I'm just a general fan of their tones.
