Kooks sometimes just sells the headers alone, without a connection pipe/y-pipe and sells them seperatly, as a lot of people like to fab up their own. the 2" primary header costs so much because a lot more of r&d goes into that particular header, as clearances are extra tight with the big primaries.
I've said this before and will say it again.... 1 7/8 =  . I don't think any ls3 motor deserves 1 3/4 headers. and if you need 2" primary headers, you are making one serious motor and probably don't need to bother asking if you need them, because you should already know that much if you are building a motor that badass |
yea 1 7/8 is all ive been looking at.. thought 2" but for only maybe 550whp to 600wHP 2" going to kill more low end then what it make up for it top end im thinking.. one shop said 2" for like 800HP.
