It certainly is a much cheaper proposition than the IXIL's offered on Taobao for the CF650's, but feel it's worth it. If it works great, if not I'll send it back and then consider if I'll go with an IXIL at triple to four times the price.



I plan to disconnect the battery for at least 10 minutes after fitting, then reconnecting to see if the ECU/ECM recalibtrates itself.

Why on earth would you want to put a Chinese made muffler on your bike? Chances are it's loud and runs straight through robs your bike of lots of torque and makes it fail emissions and annual inspection. Also I doubt that the ECU can deal with the changes and would need a complete remap. However it might make your bike sound deeper and louder.

Personally I'd only consider a Scorpion exhaust that's specifically designed for the bike, but even for that I'd need to know how much weight I would save and any dyno proven any increase torque and power before I bought it, they're not providing that information so I'd avoid that too for now.
