Exhaust reco for scrambler build on TMX 125

Hi, I went from scooters to manual and so far nag D-DIY ako ng scrambler na TMX. Yung nakuha kong TMX ay naka kalkal ang pipe and I'm not a fan of loud exhuasts.

May ma rerecommend ba kayong pipe para sa tmx125 na tahimik? At anong kaibahan ng chicken pipe at bullet pipe?
