My exhaust manifold is a four branch, each one separate. So what's the big deal? They will only fit back through the hole in the body and attach to the engine in a particular order. I was warned ahead of time so I took photos, marked each pipe 1 thru 4 and made note of how they came off the engine and out the hole.
2 weeks later when I put it back together I figured how hard can that be, 30 frustrating minutes later I was referring to my notes and photos.
