Ok, if you're not getting increased gas mileage, it's because it's so much fun, you can't keep your foot out of it! I was concerned about additional noise, but there really is none on my 2003 4 Runner, until you punch it, then it's really throaty. My mileage has gone up about 1. The performance is immediate, and very apparent, most notably response time seems instant, no lag. Increased torque and hp you can feel. Oh, my mechanic said it was a bear to put on, and didn't fit easily.
