mine are 1 3/4, 3" collector and cats, 2.5" behind the cats to the 3" merge pipe.
1 3/4 best for my truck without FI.
They make 1 7/8 for 6.2 and if you are going FI.

What's the price difference between the two? I know Dynatechs are pricey. Those are nice looking headers though, I want a set.

why did you reduce the pipe to 2.5 post cats?

Today on the highway I got on it and the pacesetter all 3" piping really made a difference on the top end over the smaller collectors and 2.5" piping on the OBX.
