Exceeded my expectations!! Very noticeable increase in power and torque in high rpm range. My car feels like it has come to life! Don't even know it's there until you push the peddle down and watch the hear the transformation from minivan to sports car! It sounds awesome!! I highly recommend this to anyone regardless of car make or model. I should have installed one a long time ago. Great product!!! I actually feel about 20 years younger when driving now, and I'm 47! Thanks!!!!!!!
