I actually notice the increase in horsepower, the sound is pretty damn awesome, probably the best single upgrade for a car.

it arrived on date as promised, I felt like a kid at Christmas once I opened the box. Installation time was All of 40 minutes, the sound was nice not to mention the extra power, along with the difference in gas saving, truly unbelievable. Glad that I did my research, and made my purchase.
