Fit and finish is really good. I've installed headers before, but this time I had a shop do it. The only issue was removing the factory studs (from what they said). There was a small burr from the coating on the flange. Easily removed with a Dremel or similar. Just cruising it doesn't any louder, a little growl when getting on it. Definitely felt like there was more bottom end.
