Yes the Pro Circuit T-4 Exhaust system is loud, i had it recorded by a cop and mine wide open was at a little over 98 db. It will fit the crf230f. If you want it even louder than normal you can take the packing out of it, but you will have problems starting your bike both cold and hot. And you will slowely tare up the engine because lack of back pressure.
