Hi steely Dan.
The pipe in question, about 1" diameter, stainless, is part of the plumbing that feeds recirculated exhaust gasses from the EGR valve at the back of the engine, round to the throttle control body on the front. Where those gasses feed into the inlet.
On my car (see signature line) the oil filter upper casing, the part you unscrew and withdraw with the filter body attached, does come off OK without the need to remove the EGR pipe. The filter body does need to be angled and wiggled slightly to get it past the pipe. But the pipe stays in situ. That does mean though that you need to lay down plenty of absorbent rags or cloths, prior to actually withdrawing the filter, to catch the dribbles as you wiggle the filter up past this pipe.
Like The Hood and others, I do oil and filter changes every 9000 miles max. So I've done the filter extract and replace at least a dozen times now on the Yeti. Plenty more anticipated as I'm currently expecting to keep the Yeti well past the 200,000 mark. Still nowhere near as awkward to do as a Ren-oh Scenic though! But by contrast, the oil filter at least on my BMW is a doddle to extract. I wish the air filter was as accessible as the Yeti's though.
