Took me a little over 2 hours to install. Instructions were clear. Looks great. Don't notice anything at idle or normal driving. But once you put your foot down it comes to life and sounds great. Not sure about horsepower as car is pretty quick already but I love the much added growl it gives when you ask for it. No regrets. For the price it is a must.
