Message: I've got a 2001 4.7. Can you start from the
headers and describe the pipe dimensions
and the cat size you would use. Keeping in
mind that I want to keep the pre-cats in. My
muffler guy thinks it's a waste of time. I know
you have analyzed it. Keeping in mind that it is
a N/A setup. Thanks Duner.
