Thers the F/M 40's Delta Flow race Mufflers and then another one i found was the F/M 40 Super 40's..im sure theres others....which ones should i be looking for..lemme know

 

Thanks

The 40-series is designed for maximum resonance, the Super-40s are as loud as the 40-series but deeper sounding. The Delta-Flows are designed to cancel a lot of that resonance/drone out and be much quieter.

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.

if you go to flowmasters website they have clips off all their mufflers and a basic run down on them

I put the Delt 40s 3" I/O on mine. It sounds great to me. Here is a video of mine: http://videos.streetfire.net/search/silver...eba0adbb1a9.htm
