Exhaust Notes - A Blog from MSN Autos - MSN Autos
We as 911 owners have a love affair with the sound of the flat 6. While I enjoyed this article, I reallly doubt much research went into it. Seems someone when on a Youtube search and found 10 cars in 20 minutes. Seems most have modifications which makes it hard to compare. Some are being driven, other at a stop. My 911 with SSI's and a Magnaflow dual exhaust would give any of these a run for the money and its not costing over $100k
