I purchased these from an estate.  I am not sure if these were made for both cars and trucks.  Please make sure you do your homework to make sure they fit.  The can length is 20 1/2" by 5 1/2' diameter.  The overall length including the short end (tail pipe end) is approximately 21 3/8".  The exhaust pipe input is 1 7/8" with adapter/flange and the tail pipe is 1 1/2".  NOTE that I have the adapter/flange for 3 of the mufflers.  The last one sold will not have one, it is missing. Without the adapter the exhaust input is 2".  They weigh about 6 1/2 lbs.  Also, one has a weld on an end, I am assuming this is from the factory because it has not been used.  

NOTE: the second from the top and bottom one in the first picture have sold (these were the best).  This leaves the top one (one with the weld) and the third one (one with several small dents), see the first picture.
