Now I understand things get rusty under cars, that's great but you figure the whole part, but no. I had a hole in my resonator... Ok no big deal until i found out how much it would cost to replace the exhaust system because its all one part instead of a piece by piece. Only suggestion: do a hack job, works just great for when the next part of your exhaust starts to rust and get a hole. Flex pipe as well rusted and just cut off the old one and sized to fit the universal pipe instead and just welded it on its cheaper and easier then two grand for the entire thing.
