Thanks for the pics and info. I see it is center in and this is why it needs to be shorter. I don't like drone and I can get custom mufflers made offset in and same size as factory but would cost a fair bit more.

About the DPF delete I doubt it would make more power unless tuned with more boost and fuel requiring more exhaust flow, and even then a ? A guy who works here had a turbo diesel Navara which was stock and he put a full 3 inch exhaust and deleted DPF and did a before and after dyno test and made zero difference. He later did a custom tune with more boost and fuel, which obviously made more power.
