flowmaster series 70

just wondering if anyone has tried the series 70 flowmaster muffler on a 5.4. I do a fair amount of towing, up to about 5,000 lbs, with an 03 screw and i'd like to hear it when i want to but keep quiet when cruising campgrounds. thanks for any input.

I have a 2.5" FM 70 on a 300. Quiet at idle with just a slight burble. Fairly quiet at cruise. Nice rumble when you open it up. With a 5.4 YMMV
