Just my personal opinion and we all know what opinions are like but I think every aftermarket exhaust the Navi just sounds like a fart can exhaust. Maybe it’s the CVT, no gears? I don’t know. I would love to find an exhaust that is quiet like the stock one but doesn’t look like crap…like the stock one
Look into Kenda K413, 130/70-10 for the rear. Fits stock wheel and the bike with no modifications.. more stability.. I love mine . Also yoshimura is a better exhaust . They have been around so long for a reason
