i had my cat back on for quite some time and i am noticing that th exhuast sound is coming out of one pipe and the other has the same exhust flow rate but is not giving any sound. has anyone else encountered this problem and if so how or what is the cure? i went to where i had it done and they say this has never happened and i am curious to knwo if this is something i should worry about

My Magnaflow is like that. Normal. Just the way the chambers are built inside. Same flow, slightly quieter on one side.

nah this isn't slightly quiter this is completly silent i mean not a peep even at high rpm.
