Going to see the custom exhaust fabricators tomorrow so they can put the car up on a lift to see what they are dealing with at which point they will let me know what our options are. They seem pretty optimistic they can do something for our d's.
That said, after further research I suspect without the coding to do a dpf and or urea delete exhaust options will be limited. Given where the DPF is located DP's appear out of the question without dpf tuning delete. Not sure exactly if the urea injection occurs down stream or up stream or where the nitrogen oxide sensor is in the exhaust stream, which would then determine if we would be limited to just a midpipe or midpipe and back exhaust. Hope to find out more tomorrow.
That BIG can in the lower left corner is the DPF.
