so i don't know if they really affect performance that much but it seemed that way to me on my 250, when i had the silencer attached i had to clear it out more but when it broke and was running straight off the stinger it didn't have a hickup or bog, it was nothing but power all the way through though the power band. i was running an shortened LDR blizzard silencer from feds old blaster that he had, so i'm not sure if it would make that much of a diffrence from the 200cc to the 250cc?? and if it does what would everybody recommend for a silencer for a 250cc motor
