After opening up my Wr 250f (Exhaust Baffle and Airbox Baffle) I've found it is too loud for my liking. I'd like to get a new muffler. I'm looking at the FMF Power Core IV Q or a White Brothers E-Series with the quiet core. I don't want my bike to sound like a lawnmower again, but I don't want it to be loud either. Also I like the idea of the tuneable system on the White Brothers pipe. Any advice will be helpful. Thanks in advance.
