The Brocks systems are available with a quietcore noise reduction piece . My CT Meg , is certainly loud on big throttle inputs , but when tooling around in and out of town , to and from rides , the pipe is not loud , but has a distinctive authoritative note .
I personally prefer in retrospect however , the Akrapovic full system 4-1 as the best all round full exhaust , still offering great performance and weight gains , and acceptable noise levels . Certainly compared to the stock catalytic bogged down standard system , even fitted with slipons add ons , the weight saving alone is worth a full system investment .
