Hi Lugnut;

This might help for starters: https://www.f150online.com/forums/sh...d.php?t=281389

If you prefer the Flowmaster sound, then stick with it. That's a very subjective thing, and at the end of the day, you need to be happy.

Utopia would be to find an exhaust shop willing to work with you and allow you to try each one... Those guys with close friends or family in the bidness sure are lucky ...

Good luck.

Cheers

What about a diff. 50, or the areo turbine muffler? any sound clips for all three. thanks
