Would be good to add a baffle to it as any 125cc doesn’t like riding without a baffle , then again you will get hard evidence when you take it to a Dyno Shop and they will tell you how much HP was lost using that can vs keeping a standard can vs using a harley factory can (has to be a factory can , not some aftermarket harley can)
