This seat came to us having already received extensive modificatons. The car was producing super power but had some nasty flat spots in it’s torque curve due to some air restrictions. It already had a very free flowing exhaust on so the only area to improve on was to remove the cat. The induction kit currently on the car left the air filter sitting in the engine bay amongst all the hot air, so we divised a kit that would move the filter to a high pressure air pocket in the inner wing fed by an air vent in the front bumper. Like most modern diesels with this level of work it drives like a Supercar but still returns reasonable fuel economy.
