After time some tend to crack around the flange and if you don't have access to a good welder or TR guy is maybe easier for some to just order a new one. I had one crack on me at the finish line while racing a LS1 Z for $200. Beat him by a fender. Second one to crack in my TR endeavors...
I have a ATR crossover pipe with Postons headers. The damn pipe keeps leaking . Called Poston and they say there on back order and have no clue when they are coming in.
