Depends what you mean by 'double exhaust pipe'. If you just mean a new tip on the end, then a few quid. But if you mean a full double piped exhaust system (which I've never heard done on a Stilo) then several hundred.

Most people go with a stainless cat-back system (single pipe to the rear of the back box) and choose from a choice of tailpipes. Most systems are guaranteed for the life of the car.
