It took me about 4 hours to put on, but I'm sure it could be done quicker if you're familiar with the tank removal process. I definitely noticed better throttle response and better sound from my exhaust. Everytime I turn the bike on, you can hear the whistling of the highflow air filters, but it calms down after the bike warms up. I've only had them on for 3 days now, so the sound might go away permanently. Overall, I love this set up and was glad to throw away so much stuff in and around the airbox, cluttering up my bike.
