The 3 valve V-10 has very good exhaust flow compared to the 2 valve. The 2 valve was designed to fit into vans, and was very restrictive. The exhaust manifold bolt problem was also addressed. If I had a 3 valve engine, I would not do anything to the exhaust system unless I was doing engine/head work that required more exhaust flow.
