Honestly, IMO Flows sound like crap on a 6 cylinder. It depends on what kind of sound you're after, but they sound really raspy on 6 cylinders. Chambered mufflers in general don't work well with 6 cyls and 4 cyls. They tend to be too raspy for them. I think you're better off with Walker Dynomaxes, Magnaflows, or something similar. You definately need true dual exhaust, if you don't you'll sound just like any import with a coffee can exhaust. There are plenty of sound clips on the net, you should do a search and find sites that let you download them.
