theres been a few how-to's on 3-1 and 4-1 collectors, but does anyone have a how-to on making a 6-1 collector or instrctions/pics on making one? any help would be greatly appreciated. thanks

 

Following my tutorial https://honda-tech.com/zerothread?id=1761667 you would make the marks/cuts at 60 degrees on each side instead of 30 (as seen on step 4)

You will get 6 pipes with 60 degree sections of the circle, when put together all 6 will make 360 degrees.
