I have a dsp exhaust system on my 01 yz 250f and its served me very well over a few years. Then, while at a race the metal baffle inside the pipe that the packing wraps around broke into 5 separate pieces. so i rode the moto sounding like a race car with open headers.lol. i need to know were i can get the metal thats inside the cannister. the pipe is simmilar to the fmf factory 4 setup, but iv called up all the companies and they wont do anything but try and sell me a new exhaust setup.i just cant find any sheet metal that has holes already in it. Please help me out!!!!!!! thanx!
