On my Tundra I installed a K&N FIPK intake system and an off road free flow muffler. I think the loud noise "tricked" me into thinking that it had more power than reality. Where it made a difference was hauling heavy items up hill. As for the MPG, I got an average of 15 before the "upgrades and got 15 after. I will admit that I gunned the accelerator often because I liked the sound. Also, my driving habits may have chnged for the worse to evoke the loud rumble as well. Nonetheless, I do plan on getting a cat back system for the H2 but i won't mess with the intake. Too loud!
