Each X-OST Sport Exhaust system is made at its engineering center in Maranello Italy. Every
new model is track tested by former F1 driver Domenico Schiattarella for performance, sound
and reliability.

All X-OST mufflers are available in two sound levels. SPORT and RACE.
SPORT gives the car a louder, more aggressive tone over factory mufflers with no resonance
in the interior of the car. In some cases as much as 35% more sound than stock.
RACE has an even deeper, more aggressive tone than SPORT but not overly exaggerated as
to make it uncomfortable inside the car. It is a great compliment between street and track.
Some versions can be 50% louder than factory.

There is also a LEMANS version available on some models if you require no sound muffling. This
is recommended only for track use.
