Why would insurance care? That's absurd.

In the US, it has to be proven that the aftermarket part caused the failure. Example, the new exhaust was touching and burned a wire up. They can't deny warranty on say, your radio screen going out because of it. And frankly they likely can't deny engine warranty due to an exhaust, because by far the main contribution to the exhaust restriction is the turbos. Everything after the turbos and cats is basically irrelevant as far as a restriction.

That said, people have said the S68 does some efficiency stuff that makes it sound like crap, and that's why they went with the quiet exhaust and fake sounds.
