I ordered the Summit H pipe kit along with the full exhaust system. With both kits you can place the H pipe almost anywhere you want. Prefitting the exhaust system without cutting it for the H pipe gave me my first clue that I had a pipe to header fitment problem. The H pipe kit really didn't change the fitment issue. The angles of the bends in the muffler to header pipe were the issue. I used jack stands to hold the pipes in place while I did the mock up and then tack welded each piece before lowering the system in order to weld each joint.
