2016 LML DPF on a 2014

[papy]

hi folks,

 

i have a 2014 gmc 3500HD long box 6.6 LML that has been deleted from the previous owner. I am scrambling around looking for  a 2011-14 DPF and catalytic converter for my truck and was  wondering if anyone knows if the 2015-16 LML emissions will work on the previous GEN body style? 

 

i know the down pipe on the 11-14 has a clamp on flange for the turbo and the 15-16 has a 3 bolt flange. this can be fix by way of changing out the down pipe ( would rather not) however mostly wondering about the system functioning as it should. 

 

thanks
