I have really been considering the Dinan upgrade so I stopped by the dealer today to see if I could make a deal. Just so happened that the Dinan rep was there with his 5 series. His car was equipped with the stage 2 that provided I think 6 more hp and a few extra pounds of torque over stage 1. Now the test drive!! I started the car and immediately noticed the Dinan exhaust. The rumble was incredible. I noticed a definite boost in power. The car accelerated much faster than stock. As we were driving I was trying to figure out how the 5 series would be compared to the larger 7. Not sure how much more a 7 weighs more than a 5, but I would guess 600-700lbs. In any case the car ran great. On the highway at 70mph and stomping the accelerator the car pulled hard. Still waiting to see if the dealer will cut me any kind of break. I won't hold my breath, but I can at least dream. I will let you know what I come up with.
