340 headers?

I've got Hooker headers on the Duster. They were on there when I got the
car 3 years ago. Dont know when they were installed. They haven't leaked
anywhere. Granted they do hang slightly low. But i thank they work great.
A buddy has a Demon with Dynomax coated headers. If he had problems I
would have heard it from him. My Hookers are getting rusty and I just might
put a set of those on.
