THIS SUPER 44 MUFFLER IS FOR SALE - Contact me for details. Please read the description. NOTE - The Super 44 is the final product. Stock start and revs, then start and revs with the Flowmaster Super 50 muffler, then start and revs with the Flowmaster Super 44 muffler - 2001 Ford Expedition 5.4L Triton V8. I finally have upgraded the exhaust system on my Expedition. I upgraded to the Super 50 Muffler by Flowmaster and noticed less than a 10% change in sound and was unhappy with it. I went back and got a Super 44 ordered and installed today. I love the sound. It sounds great outside and is not too noisy inside. I am really happy with it..the video does not do it full justice.
