im looking to sell the doanldson 51" muffler, with 4" in/out i current have on my truck. its been on there maybe 2 weeks. im looking to go back to my hog performance muffler. i wanted a quieter truck, i got it and now im not liking it. want her loud again. so if youre looking for a muffler to quiet the ol' CTD down a bit, this is what ya need. its nice at highway cruising speeds, but when you mash the peddle you def can tell its a diesel. any questions pm, its in great shape. thanks.
