"Wet-dream"TA

I'm running an lsx this will be my first FI build I'm planning on making a little over 1000hp using an f1-c procharger. I have a lot of issues of course but the current one is how big should my headers be it will be a 406 making around 15lbs of boost I have 1 3/4" longtubes now but I'm sure that's not going to cut it

1 7/8 at a minimum. Let it breathe.

Kooks 2'' primary tubes, and 3.5'' collectors.

You can't put on a header big enough. Get what I'm saying?

Let me rephrase
I'm not sure what kind of car your working on or if that 406 is a gen1 sbc........but you'll be hard pressed to find a "bolt on" header that is too big.
