I had just cat back loved the sound just wanted louder and meaner. Got new headers chased exhaust leak for weeks taking it on and off re tighten up re angle everything I could try. asked a few friends and researched here and pretty much LS engines sound like shit with headers is all there is too it as I have no black spots showing leaks and even did vacuum test and nothing. SO put cast irons back on if you cant live with it.
