Aprilia sr125 mortard (2012) Help!

there really not avalable, engine isnt one i recognise and ive had a lil search about... leave it be or buy a can and take it to a pipe maker, its a 4t, it needs a pipe to link the engine to the can, wherever you like it, wont be expensive if you dont mind where it go's just cut yours off and bolt a cheapo can on there, messure the pipe obviously befor doing this and obviously clear the ground, its not gonna do much, as no pipe will do much to a modern restricted underbuilt 4t engine.. there made to last for a little while, the way they are, and be replaced.. just like everything in this world is becomming, short lived. if it really really really has to have a pipe for self gratification/a little extra sound then go for it.. but dont expect any kind of gain other than attention
