This engine will be dual 2 1/4 dual pipes past the trans and to a good muffler for some back pressure with a single 2 1/2 tail pipe I think.Any idea what you are going to run for exhaust? Will you run true dual pipes? I think it would be cool to run them from the manifold to a y-pipe, then to one bigger single exhaust pipe, I bet it would sound tuff! What kind of mufflers?
Then with the next head being built by 66aCUDA I will put a better flow muffler on for the bigger valves and mild rv camshaft if I need too.
