Same here. Installation was super easy. Have done it with friend of mine in less than 1 hr. The only thing I would suggest to get is wider exhaust clamps. You need two of those: 2.5" and 3". Other than that is pretty much straight forward.
Quality is good. Although I would not suggest you to but black chrome tips. If you take a close look at those, color doesn't match.
From the outside the exhaust sounds amazing, but you can hear it inside as well. There is certainly noticeable amount of drone present. But I'm sure you'll get it out of any other aftermarket systems.
So my overall experience with CP-E is 3.5 out 5. A little disappointed in black chrome tips and drone.
Good luck.
