System was very easy to install. The fit was excellent and all pieces ended up right where they should to align with hangers. Welds were all sturdy and polished nicely. Went together like a glove in about an hour and a half total time. The only problemn was the five inch tip supplied did not tighten down as the clamp ran out of threads before the tip was tight enough to keep from slipping. A fine installation with great sound!
