Doing an exhaust mod for a buddy with a 2008 Dodge Ram 3500 Cummins diesel.The info center was showing a DPF full see dealer message,to get rid of that problem we decided the most economical way (not necessarily the easiest way) for the time being to gut the DPF , DOC and catalytic converter as I have all the tools,welder,plasma cutter etc. This will not only get rid of the message coming up and causing the truck to go into a reduced power state, but will also enable the installation of a Bully Dog GT tuner to do the deletes.The hardest part was to remove the platinum out of the cat in the turbo down pipe,without owning a hammer drill with a chisel I wouldn't attempt to gut it and just leave it or install an aftermarket turbo down pipe instead.
