In all fairness, you didn't run the ANSA the same as you did the Megan Racing, I noticed that right away. I'd like to have the ANSA, Megan, Magna Flow, and Flow-master all with the same configuration running similar test runs. If any of the cars are different models (Roadster vice Coupe), then the inside sound bite really doesn't compare.

Regardless, the Megan sounds more throaty but both are very nice.
