PVC at it's best, cheap and they just love em - Guinea Pig Cages

Do they chew on the plastic PVC? I know mine would! Looks great, cute piggies!

Not that I have noticed, but I just made the new cage and will keep an eye out. All I have seen is them running through them, but like you said each piggie is different. Good Luck

Update: My piggies do not seem to chew on the PVC. But that does not mean yours will not. They just run through it like a maze. They also move it around the cage to their liking.
