Just finished installation, fit and finish was very nice. I had to wiggle the hot side pipe around a bit to get it to seat good so it doesnt interfere with hitting the brake booster. (It doesnt when fully seated, there is a small gap between them) The outlet on my intercooler seems to be a bigger diameter than any of the other fittings. Had a hard time getting the clamp on it, could have almost used a very slightly larger diameter clamp but was able to use what was supplied. This kit does not come with any new o rings, i had already bought new ones for y bridge and turbo mouthpiece but the existing ones definitely would have been just fine to re use. Overall it went smooth and im very happy, kit looks great! I would definitely recommend to others and i would also buy again.
