Rather it should collect at a distance 3 times as long as the first collector. Since I don't know the port timing specs I'll just make a very general example to get the point across. If the outer runners collect at 12" to each other, then the middle runner should join in downstream at a total distance of 36". Again these aren't actual numbers just an example....

as has been noted, by me at least, several times. because yours works in the space provided and for the rules you race under. The only other way(known as you have pointed out no one has truly tried everything) besides yours to show real gains is the log tube collecting back at the cat. Anyone that has spent any time flowing them or trying some on has found the same. Paul Yaw, Racing Beat, Hymee(of the ones he tried) etc. Racing Beat legitimately makes some with the header they have out if you combine it with their whole engine back system. But it basically does what your log does in a "prettier" fashion.

Fred's quote? sure , it was long ago and without allot of the info needed. However outside of yours really its the only way(known) to make a header and see decent(relative of course) gains by itself

Lol--now there is an idea.
Sorry I should have been more specific.
I didnt want to begin with a cookie cutter tubular header. So if a certain deal works out I will have something much more specific.
It will have a burns collector--type lenght etc details to be determined by Burns. I will be using the Mazsport midpipe --its 3 inches inside the resinator-- with one of them removed, will use V band connectors throughout. I will be paying very close attention to all transitions.
I dont know if I will continue with the RB catback or not at this time. I think it will be a matter of give/take concerning it
This is a DD car with some Track day use. Yall know my engine set up..

so i would love to get the Knight Sports header, mid pipe and exhaust but were talking about 6k. I dont even know the power gains or how it sounds, but itd be cool.
Im on the hunt for a header but i just got the BHR mid pipe, if their header comes out with that included, ill have to sell it
