The shape of the trumpet now maintains a straight form to near the lip.
Increased mid-range torque was found when comparatively tested against TODA Racing's conventional trumpet with a 2.4L F20C TODA Racing specification engine.
The power curve was also found to be smoother higher up the rpm range, showing setting up of the engine map to be easier.
Also using this trumpet, increased mid range by up to 10hp, as well as 1-2kgm of improved mid range torque.
