If the 115bhp of Kawasaki’s 2009 ZX-6R isn’t enough for you, Two Brothers Exhausts has the answer.
The American firm has just launched a slip-on can it says will boost the power beyond the figure MCN measured at the rear wheel in a recent test. The can will also boosting torque and is lighter than stock.
It features Two Brothers Teflon-coated cast magnesium outlet, meaning you can fit various inserts, and it connects to the standard pipe via a thin-wall slip tube.
An aluminium version costs $1000 (about £676) and a carbon version $1100 (£744).
