Ferrari 150° Italia - vertical extension to exhaust pipe 26 November 2011
Up until now, Ferrari have managed to keep an important update to their exhausts secret. Back at August's Spa round they introduced a vertical extension to their exhaust pipe (right-hand arrows). The mounting of the extension is integrated with the section of the exhaust near the car's underbody (left-hand arrow) and is covered by the sidepods. The vertical element creates another chamber, which changes the pulse rate of the exhausts and means some flow continues when off-throttle, allowing the team to recover a little blown-exhaust effect even when standard engine maps are being used. This is an interesting experiment ahead of 2012 when 'hot' blowing - widely used this season - will be forbidden.
