Exhaust baffles, decibel killers or silencers will not make a noisy bike quiet, but should help take the edge off the noise and turn it into a deeper, more pleasant tone. Useful for track days, long rides, touring or just keeping the police and neighbours happy. Remember, baffles are usually sized based on the OUTER diameter of your exhaust pipes and the baffle itself is 2-4mm smaller for a snug fit. So if you have 2” pipes, choose baffles for 2” pipes not baffles that are 2” in diameter as they won’t fit. All the baffles on our website are described based on the size of exhaust pipes they fit - read our Guide to Exhaust Baffles for more information.
