hey chris it almost sound s as if there is something loose inside the exhaust like maybe the cat coming apart or something is that possible. as i said it sounds like chirping and only hear it when i accelerate
hard. if i just drive normal you really dont hear it. i gave up on it for awhile, got tired of R/R the header on that side so much.
