Reply to "Headers, again"

Those are what I have. IF you look at the pictures of the factory Gp4 cars, the exhausts exited where Halls do. That is in the original notch for the street headers.

What I like about them, which is what many do not, is that the left and right side headers are separate and bolt together in the center.

This is a practical solution to serviceability.

If you go to one piece headers, with the left and right side built to each other, consider how you are going to install them onto the heads.

Also consider that once the headers are run and get hot, when they cool down they warp.

The one piece will loosen up the headerbolts constantly, and if you remove them from the engine, they will be very, very difficult to reinstall because they have warped.

Halls solution is much more practical and the exhaust exit into the original location is a better solution. They are also 2" primaries, not 1-3/4". 2" is correct. 1-3/4" is not unless you are running the C302B Motorsport aluminum high port heads with the 1.60 exhaust valves.

2" is correct for a 4v iron head or my A3 heads with 1.71 exhaust valves.

Plus, you can not possibly beat Halls price.
