I have been reading and watching everything I can on the different sizes and still not set on the 14 or 18 magnaflow. I have enjoyed it stock long enough. Last truck had a flow master with drone so want to try something different. After a while all the videos sound the same. How is the drone on the 14"?
I think that is a fantastic deal on that muffler. Welded in is no big issue really, only need to grind off the welds and work the inside pieces out of the muffler. A little cleaning up and you got a new muffler.
