440 headers and exhaust

Headers from 1971 dodge demon 440 rb big block
Stahl 2 inch fender well headers with slip on collectors.
4 inch collectors to 4 inch pipe that dumps between back of door and tire.
4 inch flowmaster mufflers, system held together by band clamps and welds also has o2 bungs welded into collectors one in each. There is header wrap on most of the headers which dramatically cut down on under hood temperatures some of it may need replaced, there is also heat shields on a few pipes where I thought it was necessary. There are a few places where the tube were slightly adjusted for fitment (nothing drastic). Pipe for cylinder 8 was fixed ( tig welded not mig welded). Did not have to pull motor or loosen motor mount to take headers out or put them in. On passenger side I put a small (1/4 inch ) tack weld to hold into collector. The reason I am changing the exhaust is to make the car quieter.
Please look at pictures if you have any question please ask.
Would like to sell locally or you can pick up. Would consider dropping of at a pack and ship place for you but the shipping would extra and probably expensive. Zip code 19351 Southeast Pa. near MD. and DE.
