This product has worked very well on my 05 Accord. Two circular connectors are not included, but you don't need them. Also, the shock is rotated 180 degrees compared to the stock model, but again, that doesn't matter. Judging by some other reviews, some people were confused. To remove the old mufflers, all you need is a screwdriver to slide the plastic clip off the round end of the connector and then remove the muffler. The other end is simply held in place with two screws. New shocks are installed the same way, securing with two bolts and simply snapping the other end on. It took me about 5 minutes to uninstall the old ones and install the new ones. Good product and a lot cheaper than what you can buy in store.
