The Razor Tip Slipon exhaust for the Ninja 300 is a cost-effective solution to open up that bit of peak power hindered by the factory silencer and make some more noise at the same time.. The engine + Razor combination sounds "meaty" and offers a "throaty" punch. These Razor Canisters also have optional DB Killers available for them so you don't always have to brap around town if you don't want to!
