This kit took me about 90 minutes to install from the gathering of my tools to cleaning up and taking it for a spin. The instructions were very precise and all parts were of high quality to ease in the installation process. I've noticed more power on the low end and most of all the aggressive, race-inspired growl coming from under the hood is one to let you know the engine is performing more to its potential. Great product and company to order from. I highly recommend.
