Does anyone have experience with AA's headers? They seem on-par with Euro headers.

If fit isn't a concern, the price also seems competitive with used Euro headers. AA also includes new hardware.
So why would one get used Euro headers over AA?

Following the famed BMW E46 M3 CSL headers, each individual header runner of the Active Autowerke header is cut to a matched equal length to ensure a consistent exhaust scavenging (tolerance in lengths vary by bends to a mean average of 10-20mm).
Each and every BMW E46 M3 header is test fitted to an actual BMW E46 M3 motor stand.
