Agree on the "sound" portion in regards to headers.
Alfa's original cast iron headers are sequenced with the firing order so that alternate pulses come out of the two branches and it generates that unique Alfa pulsating sound when an exhaust system is set up right.
My GTV has the cast iron headers, an Abarth front resonator, a Centerline Magnaflow center muffler and Centerline's stinger. Sounds fantastic and it isn't too loud. My duetto is about to get an identical set up.
