Marks primary pipes looks good but it's a 4-1 manifold witch is bad for midrange torque needed in a performance street 131! Marks primary who is angled upwards and the Spanish secondary would make a good header! Perhaps I will be forced to build my own header witch I really don't have time for!. Sorry guys for being picky but I want a header that doesn't produce less HP than OE manifold!

The length is critical and 4-2-1 makes getting the lengths right more difficult. I dont believe that Allison header above is equal length just look how long number 3 pipe is. Make sure your pipes firing order is right it should fire in a circular pattern 4-1. In a 4-2-1 the 1-4 should link and the 2-3 should link. Work it out from the firing order 1342. I have seen photo of a works rally car from the 70's with extremely long pipes maybe 2-2.5m long 4-1, but also the midrange set ups on rally cars
