My dad has a KTM excf350 with a FMF 4.1, its insanely loud, I have a sherco SEF 300 and my Akropovic without the baffle is the same volume as the FMF with the baffle in.
It’s crazy the difference they make in terms of not just sound but power as well. I found the FMF to make the acceleration much sharper. The baffle does crazy things to sound and power as well.
