Which headers? - ZR-1 Net Registry Forums

These headers on Tepepmeie's 703hp 427 LT5 are the best appearing headers for the LT5.
Quote from said member I believe they are ex-Baker racing headers from the road racing program in the 90's. Had them re-coated this year. 2 in. primaries / 28 in. long. They fit in a C4, I had them in my 91 previously. Torque is improved over the standard Watson/Jeals.

These headers supported 703 on the engine dyno, or 640 rwhp on the chassis dyno,corrected.

These headers would provide for power increases in a narrow rpm band because of their equal length, or near equal length primaries, the other headers I have seen have unequal length primaries lending themselves to a more broad power band.
I could be argued that unequal length headers could be better for a street car, and vice-versa. Certainly ANY sort of tubular exhaust header is better than the stock manifolds.

I would love to see some video so we could here the idle of that car once he gets her all tuned up. Heck even untuned, I love to hear a clip.

Stainless Works LT5 headers (both)

OBX LT5 header

Here is a Jeal header
