Deep within the heart of every Volvo S80 fitted with a V8 engine, lives a V8 engine. Surprising, I know. And when you disconnect the exhaust pipes on an otherwise bone-standard Volvo S80 V8, you unleash the eight-cylindered beast that lives with in. And it bellows like a monster.

Truth be told, it shouldn't be too surprising that a Volvo S80 with the V8 sounds like the angry demon of your dreams once you remove the choking exhaust that normally belongs on a staid, Swedish family sedan. That's because you may know this V8 from another application.

No, not the Volvo XC90. The Noble M600.

If I go silent for a while, it's just because I'm spending the rest of the day trying to figure out why Volvo didn't fit straight pipes as a standard option.
