Anyone aware of any negative with a simple muffler replacement? I'm seeking a bit more exhaust signature with a Magnaflow 3"/3" in/out, but not familiar enough with the modern direct injection. I am assuming that the upstream cats take care of all the closed loop fuel management. Thus a bit less backpressure is no issue. I had previously run similarly with a 6.0 gasser and the acoustics were excellent. Magnaflow model 11229 planned.
