what size headers?

[zo what]

gonna be doing long tubes soon, but was not sure what size to go with. i was thinking the 1 3/4. the car makes 516rwhp 566rwtq with the stock manifolds. i was leaning towards the hooker headers but did not see the 1 3/4 size on the website. what would be the better size to go with? thanks guys

anybody?

some guys have 1-3/4 some have 1 and 5/8th's ( thats what i have) some guys have bigger.. Pretty well anything other then stock in a long tubes will get you there.

The common sizes for our cars are 1 7/8", 1 3/4", and 1 5/8". I went with the 1 5/8" because I plan to keep my boost levels under 20 pounds. For higher boost applications, you will benefit more from the larger diameter headers...

I have Kook's 1 5/8" but would go with Kook's 1 3/4" with 3" collectors, Kook's X-pipe and SW cat back if I had to do it over again.
