Not to step on anyone's toes that has/sells MBRP, but I figured I'd post a pic of my Banks DPF back exhaust.
Also, no way no how will a DPF back void any part of your warranty. It's purely aesthetic with NO change to performance or how the truck runs. On top of that, my truck is at the dealer as we speak having the transmission valve body replaced (hesitates in 3rd gear). The DPF back, lift, and all are installed on the truck. If anything the dealer compliments on all of it.
VS when it was all stock
That being said, while I do love how the Banks kit looks on the truck, I might be more apt to choose MBRP the 2nd time around, only because they seem more involved in the community. Just sayin.. I will however go with the MBRP DPF delete when and IF I ever go with a programmer and delete pipe.
