I'm assuming you got there y-pipe too? I liked the pacesetters as long as they are coated. They fit perfectly and they do the job! I would personally go over to a GM Dealership and pick up a set of new 02 sensors if yours are original. Also you'll need a pair of 24" 02 extensions you can get from Summit for a few bucks. Also if you haven't pick up a set of Stage 8 locking bolts or ARP bolts to use. The ones in the box are decent I think. Other then that you are pretty much set their gaskets they provide are pretty good too.
