Great looking under the hood. Most difficult part of the install is shoehorning the heat shield into place. I would suggest taking the battery completely out to do this. Otherwise very happy! No real difference in power that I can tell, maybe a hair more responsiveness (its only a Civic after all) but the sound above 3k RPM is awesome. Not sure about mileage improvements yet.
