Just because you're rocking a little bike doesn't mean you can't have big power. Jardine's full exhaust system for the Ninja 250 features stainless steel headers and a carbon fiber silencer to reduce overall weight and add power (without any rejetting necessary). We installed this very pipe on a test bike and had great results: We gained five extra horsepower and reduced weight while adding killer looks and sound. The RT5 is also available with an aluminum finish or as a slip-on for a little less cash.
