Hi guys,
I am nearing completion of my 1965 Mustang Inline 6 200 coupe resto-mod and it does not have an exhaust system.
There is no exhaust manifold or headers on the car now, and my question is which should I put on? Headers or a manifold?
Car will be my daily driver so I'm much more concerned with reliability and fuel economy than power.
Your choice. I have stock manifold on my stock engine and header on my modified engine. You may see a slight improvement with a header on the stock engine, but the real problem with the I6 is the restrictive flow of the one piece head/intake design.
