What a well thought out and executed product! Sal and Evolve are raising the standards for testing and transparency. I have VERY rarely (Audi, Subaru, BMW) seen any tuner/manufacturer post this much information on a system they designed and released. Not to mention that a lot of the data is beneficial to the community, regardless of the Evolve exhaust. It's just a great contribution and product.
I'd love to see the same thing done on the intake side : )
Making me think twice about my fabspeed+akra setup...jerks! : P
Sal - FYI, picking up an X5 35d this month. Will hit you guys up once broken in for a tune : )
