so theres always something. i just got my GReddy cat back the other day and went to install it this weekend and the flanges are mangled. how they did that i have no idea, but theres no way its gonna seal. at this point i think im just gonna bring it to a muffler shop and have them intall it. unless someone has a great idea for flatining the flanges so that they sit flush.
