It's all about balance,.. matching the in, to the out... Better breathing can increase HP's,.. but only by allowing more fuel burn, which requires mores fuel (rejet)... without rejet, you're just getting more air, making you lean,... you have to match that extra air with extra fuel... ...but,... you pay for more HP peak by having a narrower torque/power band... and torque is what gives you that sweet kick in the pants launch... ... a Stock Harley Sportster muffler is a popular swap on our bikes,... Yes, rejet,... ... and you get nice sound, and better breathing, while keeping a wide power band...
