I always thought they measured ID, but i could be wrong..

Tubing is measured by the outside diameter. Pipe is measured by the inside diameter

Yep,i called QTP,KOOKS and Lemons.Headers are measured O.D. So if you are looking for a 1 7/8 header you should get a 2' i guess.I just feel like i was uninformed when i bought and thought others should know......

Interesting fact, I never knew this before I read this thread. Good question chevyman!

Not true, my Hooker 1 7/8s are 1 7/8s on the inside. My previous LPP stainless 1 3/4 were 1 5/8s on the inside. So not all headers are created equal.

Thats good to know also.Someone should make a list of headers that are what they say they are......Then everyone could make an informed decision on headers...

I heard this about the TSP 1 7/8" headers as well. 1 3/4" on the ID.

I thought they were measured ID as well. Good to know the Hookers are measured by ID.

Steve, where'd you pick up your Hookers that you said you got a great deal on?
