I ran over something on the highway yesterday that ripped a hole in the passenger side "flex pipe" portion of the y-pipe connecting the catalytic converters to the muffler.
I don't even know how to search for the part that needs to be replaced in order to make sure the mechanic is quoting me honestly. He said the entire y-pipe connecting the cat converters to the muffler is a one-piece assembly, and the whole thing needs to be replaced. Any help here?
