How exactly does the exhaust system (silencer) affect the fuel efficiency of a bike?
Ah, I see. So, would removing the silencer increase fuel efficiency?
It's possible that removing the silencer might increase fuel efficiency by reducing back pressure in the exhaust system, but it could also make the bike louder and potentially alter its emission levels. It's important to check local regulations and consult with a mechanic before making any modifications.
