I have a Perrin 2.5" resonated exhaust and it is overall very good. I do, however get a low frequency resonance between around 2700 and 3200 rpms that is more intrusive than any other rpms. Is this experienced by others with the Perrin? I have no other exhaust modifications. Thank you for your thoughts.
