Exhaust Manifold
 

Took my car to the dealership since all of a sudden my exhaust sounded way too loud and throaty. They told me today that it is my exhaust manifold and it will be over $1500. I said, "Hell no!" Right now, I'm really pissed. Any suggestions for me repairing. I have worked on cars for years and was wondering if I could replace with headers. Any suggestions would be very helpful.
