Lt500 only makes noise at silencer
« on: June 24, 2013, 05:14:18 am »
So my 500 seems to run fine but it only makes noise out of the silencer, there is hardly any ping in the head pipe. I'm not sure what kind of head pipe it is. There are no markings at all and it's coated in some black dressing. Someone on another site guessed that it may be a cobra pipe. It has always bothered me that hardly any noise comes from the head pipe. Any ideas?

That head pipe looks exactly like the old school FMF I had for my zilla.

 Whatever it is.. It looks like one of the old school copycat torque pipes.  If its really heavy it may be double walled.  Dont know if there were any aftermarket pipes that are or were double walled.  I know that does muffle the ping ping sound coming out the cylinder.

Yeah, the previous owner thought it would be cool to put a cometic sticker on there. I am currently running the same head pipe but swapped the silencer for a Bills Pipe silencer that was lying around. I still havent found out what kind of head pipe that is, its driving me nuts.
