2001 RM250 silencer sound comparison, Pro Circuit 304 and FMF Turbinecore 2 Spark Arrestor.

In the process of reviving a 2001 RM250 into an Enduro/Hare Scramble Bike, and wanted to compare the old Pro Circuit 304 silencer to the new FMF Turbinecore 2 Spark Arrestor silencer. Stock bike, FMF Fatty Pipe, still burning out old, unknown oils, so she smokes a good bit. Running Bel Ray H1-R premix. I also weighed both, the Pro Circuit was 2lb 4oz and the FMF Turbinecore 2 was 2lb 9oz.

Tested at 20", 45 degree angle from exhaust tip, about 3400 rpm, not the most scientific(cell phone decibel meter app).

Result: Pro Circuit 109-112db and FMF Turbinecore 2 100-104db.

Rider: 49 year old, fat, formerly fast, now slow, enduro and GNCC rider.
