Hey all again my last topic was fitting a gold star silencer on to my euro4 2017 B 5 bullet got a great reply from our hosts but did not ask while l change silencer would it be better if did downpipe as well l no it would be expensive but would the bike run better and quicker with no adverse affects on ecu and running or should l just change silencer any advice
