I tend to agree that 7/8" primaries are too large for a naturally aspirated 6.2L motor. I would bet the 3/4" primaries would out perform the 7/8" primaries on a naturally aspirated Raptor.

I'm glad the question was asked and you guys cleared that up. I'm getting ready to purchase headers and was unsure whether to get the 1 3/4 or 1 7/8. Thanks guys!

why would you get headers and put the stock exhaust on? why not put just a cat back on get the better mileage and not worry about voiding your warranty.

In that application you should be getting the evac you need to make it work. but to put headers on with the same exhaust system don't make sense. the faster you can get exhaust away the better.

Adding long tube headers adds more hp than a cat back exhaust system. Obviously the two together is the ultimate. But headers first in my opinion
