Attention 7.3l owners!

I have 3 Ford 7.3 Powerstrokes, 2 for business and I just picked up a 99 Superduty DRW with 150000 miles with a bad converter that had the marble sounds. The 99 is stock except for Hydra chip with set of gauges and I installed a muti disk converter plus 6.0 cooler. I paid four thousand for the 99 because every one was afraid of the noise converter made. I new the seller well and the truck was well taken care of but the noise was the kicker. I also installed the 05 superduty headlights after cutting out the header with a template to follow.
