Hello I have a 2000 YZ295 and LOVE IT! Before I sent off my head and cylinder I hade the SST pipe and Powercore 2 exhaust set up. Seeing that SST was the worst thing I could possibly have on with my EG295 I had to store it. I switched back over to my full stock set up since my fmf silencer had holes all around it from corrosion. Im going to try and make my own silencer and a carbon fiber tip since I have always wanted to see how carbon fiber is. Im currently going to school for machining so making brackets and such wont be a problem. My question is, does the actual diameter of the silencer make a difference, I know length does. Also the tube in the inside does the size of that matter and do the size of all those holes make a difference. I would like to get this to perform like stock and mabey better. I might have missed some things. any input will help me with my future project!
