Magnaflow cat back
How's the cab noise at 45MPH and below? How's the noise at 1st and 2nd gear? I am planning on a Magnaflow exhaust, but it's the low speed range that rumbles my wife inside. If that quiets up a bit too it will be a winner. I like the throaty growl as does my 5 yo but mom's not so tuned to the Hot Rod sound.
I just had the exhaust system put on my 2005 4.7L QC. I had the 50 Series Delta Flow Flowmaster mufffler. I had it for 2 days and the droning in the cab was driving me nuts. It did sound kick *** on the outside but on the inside it was like someone putting a drill bit in my temple until you hit highway speeds. Not practical for the stop and go I do. I went back 2 days later and the Muffler Shop was nice enough to swap the Flowmaster for the Magnaflow SI/DO. That thing sounds awesome. No in Cab Drone and a nice rumble on the outside. Adult loud if you know what I mean. I am glad I made the switch.
I put on a magnaflow system from the cat back and I and the wife love it. No problems at stop an go with too much noise . Just added Gibson headers and just made it a little louder but I like the attention!

Did you install the cat back using the single in and single out or the duals? Did you also use the stock "headers" or change them out as well? I am considering changing to the same one that you installed, but wanted to know how you like it so far.
