Many of them comment on the annoying drone of the Flowmasters that I experienced at highway speeds.

Thx again, Ed. I’m going to go straight out the back with a smaller pipe (2 1/4 or 2 1/2). Also, not sure I’ll be doing any highway driving so think I’m going to try the 40’s and work my way down if I find them too loud.
