I recently changed out my stock pully with a UR lightweight pulley

The reason i replaced the stock pulley was because it was wobbling alot

The new lighweight pulley still wobbles any one know what could be causing this?

and also i hear a sound like ..hissing mixed with rattling ive been told its te Bpipe on the exhaust ...but it only started immediatly after installing my headers... any ideas??

i also hear a chirping sound that comes from where the slave clutch is

any Info woul be appreciated


Thanks
