They work but have issues.
First set I bought had terrible chrome blemishes. I had a cruise-in that weekend so thankfully I was able to rotate the worst of it to the inside, and Speedway discounted them for me. Then I'm not sure if it was the tolerance on the header collector (purchased from Speedway# or the inside diameter on the extension, but even though it was clamped down as hard as possible it slipped off while driving and was ruined. I purchased another pair #chrome still had blemishes but not as bad), installed them, and noticed they were slipping off as well so I had to drill and put set-screws through them to keep them on.
