Install was on a 2013 allroad 2.0T. I am very pleased with the quality. Had to get the impact out to get those clamps tightened so it wouldn’t move. HFC /down pipe is 5 lbs less than stock. Which helps with the 15lbs added from intercooler upgrade. I feel parts and stage 2 really opened up ECS intercooler/charge pipe kit. Turbo sounds louder now. No exhaust sound at 75mph at all. Love it. I have never in 25 yrs of wrenching tuned a car, a little patience and it was easy to follow directions. TPMS did come on. I had checked my tires that morning, so I just went in and saved current pressures and it went away right away. Future plans for IE intake manifold. Great products guys!
