HA! You were probably thinking you were going to see some stupid thread like “..what’s the best header..” or some dumb $h!t like that but no, this is a different question. Have any of you who have done your header already ever looked in it to see how its bottle necked? I’m going to post up a “graph” and let me know how your aftermarket header was constructed. (pardon the Microsoft paint diagram i wipped up)

Do you know anything about fluid dynamics?

Papolito

Yes, but I’m interested in seeing how hi end aftermarket headers applied the physics of fluid dynamics. (IE. how much of a lip if any was used)

this should be interesting

Anyone got a borescope?

bigmacnfries

why?

I was joking. One can't see what the OP is looking for without one. Despite the relative affordability of low end borescopes these days, I doubt anyone here has one. But if they did I guess they probably would peep inside their nice new header before they installed it. I would if I had a one.

bigmacnfries

sorry, i was asking the OP - why?

STREETWERKZ

he also doesn't know the meaning of "graph". what he posted was a diagram.

(fixed)

I was looking at a stock ap1 header and it's built like diagram B's internals, vs a Megan racing and T1R header that i also looked at that are built like diagram A.

I actually do have one. I used it back in the day when i was in construction putting myself through college. The company bought it for us, LED's and all.
