No loss of low end, thats the reason behind keeping the stock tailpipe. I also picked up about 11/2 mpg on trips. running 70 -75 getting 22 mpg which ain't to bad. If Eddie is not there talk to Greg he will do you a good job. If you would like to hear my truck and go for a ride let me know any evening after 5 30 or on the weekend if that will help you deside what you need for your truck

Which FM 50 series are you guys running, the Delta Flows or regular 50. I don't want it TOO loud but I want it to be no mistake that it is NOT stock. Still haven't decided which one I am going with yet. I like the MagnaFlow but the shops tell me although it is straight through it will be quiet. Like the DynoMax Ultra Flow but hear it is going to louder than a FM. Been thinking pretty hard about the FM 50. I'm keeping the stock tail pipe, just can't see throwing away a good 2 1/2 pipe. Also, don't think there is much benefit with a 3" mandrel bent single system since we are talking about a stock 4.6.
