Review on AP Exhaust Products XS2772 Muffler by Brent Ayyagari

This is a continuous design so it won't interfere with your exhaust flow. I bought this for my '99 Ford F-350 with a 7.3 liter diesel. When I bought the truck a few years ago it already had the stock exhaust removed and a 4 inch straight pipe turbo installed. I liked the sound, but unfortunately local law enforcement (and my neighbors) didn't like it. After a brief discussion with the man with the brand, he suggested it and was kind enough not to quote me. Apparently he also loves the old Super Duty and knew it would help. I installed it myself in less than half a minute. Hour. I had to buy clips from a local auto parts store and do a little trimming of the existing system, but it's not that hard once you're familiar with the mechanic's job. The sound is still great but my neighbors and local icons are much happier. Not that I care too much, I just didn't want the punishment. lol!
