Extreme and Extreme Multi Level

Modern fuel injected bikes are generally programmed to run as “lean” as possible to reduce emissions. All GPR road legal silencers are designed so that you can fit them and use without altering the settings of the bike. However for to maximise the benefits in terms of performance and throttle response from your new exhaust a fuel commander can be a worthwhile investment for many bikes. This can become more apparent if used without the removable db reducer or under hard track use.

There are two options the Extreme for normal road use and the Extreme Multi Level for hard use and racing. Easy to fit, no computer needed and preset for your bike/exhaust combination. Find your bike in the shop area to see if we do one for your bike. Will also work with other exhausts.
