Great product but double install time. K/N should assemble the main parts, heat shield, rubber strip before shipping which would cut time in half. Also heat shield is too short for space allowed in compartment. Overall it looks and works great. Rick

The instructional pictures didn't match up exactly to my year of vehicle & the hardware kit was crap. I had to use some of my own hardware to complete the installation and the instructions don't properly identify the fasteners, etc. After a frustrating pre-assembly, the kit installed easily. My on-board computer showed an immediate increase in MPG as high as 25MPG then settled 23.8 during my first road trip. The previous high hwy MPG was 22.5. I detect no change in sound volume from my V6.
