เสียงท่อ Yamaha WR155R (exhaust sound)

[@jonathanalfred9847]

Do any of them ad any power on a dyno test ? Or is it just for a better sound ?

[@FillyBetter]

Generally switching to an aftermarket exhaust system will lead to better torque flow, enhancing power output. So to answer your question, yes.
