Here's the video I posted right after I made the swap. Honestly, the only reason I swapped was one of the Flowmasters developed a couple rust pinholes. The Pypes mufflers are stainless construction and have a lifetime warranty (I believe). Don't quote me on that though.
The biggest difference for me was the ability to now carry on a conversation in the car while cruising because the drone is completely gone. It still sounds great at idle and WOT in my humble opinion.
