Upgraded my 5.4 3v F150 from 2.25" true dual exhaust with Dynatech max long tubes and cats with super 40s to 2.5" with high flow cats and super 44s. The sound isn't as loud but more throaty with a little more rumble and the interior resonance was reduced drastically. Exhaunt flows much better now. I can't tell if my low end torque changed much but passed 4000rpm there is a big difference.

I bought this muffler in order to add a custom dual outlet exhaust to my 2013 Ford Focus Titanium hatchback that only had a single outlet exhaust as original equipment. The Flowmaster Series 80 created a low rumble at idle and a deep loud satisfying growl whenever I step on it. Just as I was wanting and without any droning and significantly quieter when I'm driving just normally for maximum MPG. The muffler arrived on time, well packed and in perfect condition. Highly recommended.
