I just put a Flo on my 6.2. It's great. It's a 40 series. Not the super 40 or 44. They used a offset/offset and about 24-in of pipe in front of it. Cost me about $150 total. It is single in single out. 3-in both sides.
There is some drone up to 40-45 mph then it drops off to very little. It is not annoying at all. Installed in same location of old muffler(under the hanger)for best support. It turns a lot of heads. Especially trucks next to me.
People even want to race me?? really in a F-350 flatbed chassis cab?
