I had a Gibson super flow extreme on my 06 F150. It was too quiet on the outside and too noisy on the inside. Couldnt stand the boooooooo sound it made (clashed with my Jams). The Flowmaster 50 HD sounds really good not too loud and the tone heard on the inside is more too the rear and just sounds better than the Gibson. The Gibson sounds like its right under where you sit. Flowmaser is a good sounding muffler.
