Thank you for sharing the photos - lots to consider and they all look amazing, very motivating for me to get this done. I do have one additional question. My current exhaust system seems to have an
air pump fitted that is connected to the
exhaust pipe. Clearly an after-market change. I was curious as to the rationale - does it improve performance or reduce the heat of the exhaust pipe (or both). I'm always startled by how hot the parts of the car get that are in proximity to the exhaust pipe and was curious as to the reason for the pump and should I try to retain it.
