This week I ordered my new exhaust system. I started out by calling Stan at Ford Powertrain Applications on Tuesday. We spoke for quite some time before settling on the right headers. They are a header he specifically mocked up and built for the 347. With my TFS heads, I had to go with the 1 5/8" primary tubes that increase to 1 3/4" within inches to the flange. The center to center stud holes on my exhaust port does not allow a 1 3/4" tube without being pinched enough to make room for the bolts. He also said the 1 3/4" primary tube headers use the same flange as the 1 5/8". I can also hog the flanges out to match my ports if need be. He asked all the questions before making his recommendations. I also purchased a power steering drop bracket just in case. The headers come with all the gaskets and bolts.
Yesterday I called summit and ordered my mufflers. I decided to go with the Dynatch split flow race mufflers. They are a 3" straight through muffler.

I also purchased a H pipe crossover.

I am tired of being screwed by so called muffler guys who do shotty work so I will be mocking my own exhaust system up and probably have some guys at work weld it up. It will be simple. Out of the headers to the H pipe and into the mufflers before exiting out in front of the rear tires. This mutha is going to be loud!
