American Racing Headers

[blueovalkid]

I am getting ready to order a set of AR headers but i'm not sure if I should get the 1 3/4 or 1 7/8. My goals for the car are around 700rwhp with a 2.9 Whipple and all the supporting mods.
I called spoke with Nick at AR and he said that I could go either way.
Any thoughts?

I have the 1-7/8 Stainless Works. They work well at the top end to keep the boost down and the temps .

The 1-3/4 also work very well from what I've seen .

If there is any difference between the two it would only show up at the top of the RPM band at the higher HP levels such as 700rwhp and the difference would be minor.

I have the 1 3/4 ARH and love them. I didn't have the choice at the time or I may have gone with the bigger just incase I wanted more down the road. I have no issue at 784 rwhp with mine though and I think Mr. Farm dog has the same ones too. My one piece of advice I give to anyone that will listen is get them coated bfore installing the first time. Sucks to pull them off to put them back on a year later!

I agree with ice. I had mine hot jet coated. It is spendy but I am glad I did. It is very durable and helps keep the engine compartment temps down.
