Quite pipe for a 2012 KX450?

[Freeride1]

Does anyone have a recommendation for a quite pipe for a 2012 KX450?

My bike isn't a KXF, it's a KTM 450 SXF and I just put a FMf Q4 on it. Had a Two Brothers slip on before and the FMF is WAY quieter and has a tone that is much easier on the ears then the TWO Bros. Sounds really nice now.
