I've had the Flow 40 Delta on my 2007, v6 Mustang for a few weeks now and they sound amazing. They are loud enough on the outside and resonate just enough on the inside to be fun and not give me a headache. I even drove from Las Vegas to Denver without any problems or annoyances. If you are looking for a great muffler with very good sound, go with this one. I searched for months before I settled on the Flow 40's and I couldn't be happier. Also cheap instal and I had a chrome tip welded on that really completes the look.
