Installation was fairly easy. It fit perfectly but it's tight. It sounds pretty much the same during normal driving, but when you step on it you can definitely hear the difference. Above 3000rpm, it felt like it was making a few more horses and the throttle response was sharper. 5000rpm butterfly valve opening was especially noticable. It added the slightest freeway drone but it's definetly tolerable. 5 stars. Highly recommended.
