I have a 2016 F350 with an S&B intake and just installed a MBRP turbo down and back exhaust. It's been 9 days since I installed it. Yesterday the truck did its exhaust clean and white smoke started pouring out of the hood. I understand that the oil from manufacturing need to burn off but I am a little worried. I contacted MBRP and told them everything and will have an engineer call me tomorrow, but I trust the things I read in here more than some guy trying to cover their ***. Thanks in advance.
You need delete tuning in order to run a full exhaust. Otherwise the truck will try and regen and cause itself harm / go into limp mode / not run at all.
Turbo back exhaust or DPF back exhaust?? Turbo back exhaust means you took your DPF off. For your truck to even run with the DPF gone, you would need delete tuning. I've never heard of a truck going into regen (cleaning exhaust filter) mode with the DPF gone and delete tuning installed. The delete tuning disables exhaust regen and other things. You've got a big problem if your DPF is gone and your truck is going into exhaust regen. I can just imagine the flames coming out the tailpipe!
No delete kit I live in California. This is supposed to be a bolt on kit. Part number MBRS 6286409. I talked to the device department again today and they said they have had a few instances where they didn't wash the oil off from pipe bending.
I haven't heard of anyone installing a bigger downpipe and doing a dpf back exhaust. Rarely do people change out the downpipe. Sounds like you either have a loose fitting somewhere on the downpipe or you melted something in the engine bay due to an exhaust leak maybe??
I don't see the point to change the downpipe, especially with the DPF on. Your not going to improve exhaust flow by doing this. The stock 4" downpipe on these trucks are good. As stated above, very few change out the downpipe.
