i just got my thorley header in, and it said it was going to the "tri y". well mine isnt. it is a 4 into 1 then has a long pipte with about a 20-30 degree bend in it to go to cat. just wondering if this is right or if i have the wrong header before i try to bolt it up.

kind off hard to make a tri y design when you have 4 primaries. my thorelys are a tri y being that they are for the v 6.

 

no....4 go into 2 Y's and those 2 Ys go into one Y.
