Replaced the OEM primary cats with the Flowmasters and got a high quality product for a very reasonable cost. Very happy with the end result.

Its what I was expecting, it did really met my expectations, I'm happy with my choice, I installed in my Mercury Mountaineer 2000 V8 5.0, I did not make any modification, and it really sounds Nice!!!! just perfect, a sound very weel balanced, not too loud for an suv, but it really let you hear the power of your engine to every one. I recommended very well. Gil.

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.
