Stainless is better for longevity than mild steel, but corrosion doesn't seem a major issue with diesels, unless you do a lot of splashing around in the shallows at the beach.
2.75" seems a less common, dearer section of pipe to get when checking out some exhaust joints.
Has anyone thought about running two smaller pipes in parallel to give a larger total bore? This would allow keeping the plumbing further off the ground than with 3" setups and more option with bends.

I don't want a big loud exhaust, I'm happy with a bit of noise increase but I just want no restrictions down there, that's what it's mainly about. I don't want to lose any low end grunt

I intend to fit the chip if I do replace/hollow out oem exhaust. Not after a massive increase in power, the chip will be set low just because I'm not after power, like I said, it's more about losing the restrictions. Christ I've waffled on a bit.
