Header install 69 Dart

Both of those are $$$ What level of motor does it have? Stock hardly benefits from headers and the trouble involved is usually not worth the gain. A pair of $$ 340 or ¢ magnum logs tied to 2.5 headpipes and dual turbo exhaust make a nice rumble. Glasspacks are an aquired taste....I had a 351C with open flanged glasspacks right off the headers and that sounded bad *** until you drove it about 10 minutes and then it was just annoying.
