Why do my exhaust manifolds look like headers?

I mean my exhaust manifolds on my old Z looked like exhaust manifolds, but on this LS1 they look like headers. Is the design better or something on the LS1?

if you have the slp options on your ss you have high flow manifolds. the look like seperate pipes coming off the heads

there is no option for a high flow manifold from SLP or anyone else.

thats just what they look like from 98-99

They are an improved design but you will still gain lots of power with Hooker Longtubes. People see as much as 25 rwhp with tuning.

No, it was never an option.
