Got an annoying rattle from the exhaust and I thought it was the usual heat shields but turns out to the outer casing of one of the cats. The exhaust is not blowing so as far as I can tell its just a shield over the cat. It looks to be aluminum and It could probably cut it off. Its fairly loose and a lot of movement on it.
Does anyone know if it would be safe to remove it, I assume its just a shield and serves no other purpose?
