I was not suggesting anyone change the entire front suspension or even change their approach. All I was asking is how much more can you gain by going to a custom header of some kind vs what you get from the stock exhaust manifold (my car has stock 5.7 exhaust manifolds). I posted the photo to show just how direct the flow will be with out using headers.
I am not a racer so 25 hp won't mean as much to me as some others,therefore the cost and hassle of the header application wouldn't be worth it to me. I will post dyno results when I get to that point with this car...maybe March sometime.
