LeoVince have thrown away the restrictive stock silencer and catalyst and replaced it with their new SBK-Underbody exhaust.
The new exhaust is claimed to weigh 20% less than the stock can, bolts to the standard chassis mountings, and connects to the stock downpipe flange.
There are carbon-fibre heat shields at the front, while the tail section has an angled carbon-fibre exit section.
LeoVince claim that torque is increased from 2800-6500rpm.
The £466 road legal exhaust has a removable baffle, and fits all Duke 690s from 2008 to 2010.
