The delta flow is definately the way to go unless you prefer the constant drone in the cab at highway speeds. I haven't put a flowmaster on my truck (yet....but it's just a matter of time) but if I did I would go with the next quieter series "50 Delta" with delta flow. There is very little, if any resonance, they are al little quieter with a nice deep note. Those along with a quality X-pipe will give it that smooth throaty sound that most people look for.

It's either that or some 12" glass packs with a shiny chunk of stove pipe hanging out the back. :D
