This is hands down the cleanest fmf exhaust system you will find for the 01-08 RM250. VERY HARD TO COME BY. FMF no longer produces the fmf factory fatty pipe for this model. Expansion Chamber has been fully restored to new, better than new actually. The pipe was in good condition to begin, was sandblasted, vaporblasted, and wheel polished, then the blue heat treatment was an additional service. Topped off with a professional ceramic coating. If you were get this service done it would be well over 600$ in addition to the cost of the pipe and silencer. Silencer has been fully vapor blasted and ceramic coated, restorer didn't fully disassemble, only exterior vapor blast, exhaust packing is relatively new.
