125-200cc Husqvarna SMS 125 2002 with CR exhaust

Hello, I have a Husqvarna SMS 125 '02. And at the moment I am running with a CR exhaust. Are there any cons using this exhaust? Will a exhaust made for SMS/WRE give better performance?

it won't give out any less performance than a pipe specifically made you the sms/ wre model, it should give you a bit more if it's jetted correctly for the pipe as the cr is more powerful as standard than the sms/wre are. Check the colour of your spark plug as if you're using the cr pipe on the sms your jetting could be lean and you will hole your piston! If it's good then there's not much point trying a specific pipe for the bike as the ones that are made are for the road legal variants rather than the cr which is completely off road
