340 - Stock Exhaust Manifolds or Headers

Been using some ceramic coated dynomax headers. Once tore open lower hanging header on a manhole that was sticking out!! At the time had 14" rallyes. Took car to my local muffler shop and they patched up the tear @ bottom of pipes. To this day still have these on my dart sport. No leaks after I went with Percys aluminum gaskets. Now also have 15" rallyes all around no more scrapping issues.
