I can assure you that on a 3.2L the bypass pipes will not cause a CEL light. I agree that the bypass and the muffler is probably enough for improved tonal quality. Maybe too much so as resonance gets old fast especially for passengers i.e., spouse or girlfriend. The header would be nice but at $2,200+ I'm not so sure it would be worth it. Am waiting for Che to finish development of his 3.2L header.
