The AMS downpipe is completely made of 304 cast stainless steel, including the flex pipe and flanges. Precise fitment is guaranateed and makes for easy installation given all the gaskets and hardware provided. AMS even incorporated a bung for a wideband gauge with a plug included, ensuring this would be the one and only down-pipe you'll ever need!
