running a rear exhaust delete on the levorg now. Much nicer. Was $400 (Australian) including tips. Not cheap, but better than 1200$ plus for a basic catback. Only chasing a little noise, not after power. https://photos.app.goo.gl/gAfcYXz6t27Yj3x33 https://photos.app.goo.gl/IVKPJFFqcl1ZlX9u2 i'll try get a video of it in motion. so far, no issues (drone etc).
