Dinan is such a waste of money, there is so much better gains for less money. Run BM3 for 2x the power and 1/2 the cost. High flow catted are not worth the money imo. The biggest gains will be with catless. Again thou Dinan is not going to push huge numbers. BM3 with catless dp would give you massive gains.

Unfortunately I already bought the Dinan 10 months ago, so no going back. It does say horsepower increase to 369, and torque to 470. Which are good gains. I need to get more information about catless. I heard going catless you get gas smell in the cabin, which I obviously don't want.
