This Adjustable Baffle Exhaust is Crazy
The system has been developed in Asia and allows the rider to modify the volume of the exhaust on the fly
If you ride trackdays in the UK, the chances are you have a totally rational fear of trackside noise meters. The chap in the paddock with the microphone on a stick is much less scary - humans can be brided after all.
Artificial Intelligence, as was proven by the Terminator movies of the 90s, cannot be bribed, and does not know when to stop, and the net result could be you pipping the drive-by noise meter signalling the end of your fun on the track.
This exhaust could help you with this, as it features an in-built system that allows the rider of the bike to reduce or increase the noise of their bike while they ride. It’s the result of an Asian company called 3 Tech Racing Evolution, which makes a range of exhaust systems for small-capacity bikes and scooters.
The exhaust that caught our attention the most was the appropriately named Scorpion system. In the clip below you can see the exhaust fitted to a Honda CBR250RR, with the throttle of the bike getting blipped a few times and then left to settle at tickover. Then the handlebar-mounted lever is adjusted, removing two baffles from the exit of the exhaust and allowing the bike to breathe more freely - and loudly.
Now, having the presence of mind to actually adjust this thing as you hammer around a trackday is a far-fetched one, and a bit of a joke. In today's ever more stringent world of noise restrictions and fines for such things, having an exhaust that sounds louder when out in the sticks, and then 10 or 15dB lower when in a town or city could be a very handy thing indeed.
