But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

Installed the DPF Back system on a 2017 Ram 3500 CCSB SRW. Fits great and looks much better but thats all it is, is looks. A little costly for a glorified tailpipe but it does increase the look of the truck, but does nothing for performance, which I knew. Either way, still happy with it.
