I have a cut before my cat in my exhaust thats half way welded and i was wondering what i should do to repair it (keep in mind i want it to sound nice when i repair it ) where can i find the pip that goes from the cat to the engine does anyone know? and what should i get to make it sound nice? a new cat? a new muffler? along with the pipe to the cat from the exhaust manifold? i really want dual exhaust but i want to keep it cheap
