Read the tech tip on the project on this website. Reconsider using the split manifold. You will have to have your exhaust changed anyway since the 235 exhaust will not come straight down but back at an angle. So, it won't be too hard to have a second pipe bent while you are at the muffler shop. Believe me, there is nothing like dual exhaust on one of these puppies. Sounds grrrrrrrrreattttt!
