Ls7 exhaust manifolds modified to fit narrow chassis
Just recently took my parts to the welder and got my LS7 exhaust manifolds welded together. The large factory flange flange needed to be removed to fit the narrow chassis for the Avanti. The transition to the 2 1/2 diameter not only angles together in the horizontal in the picture, but the whole transition also angles inward toward the block, similar to a block hugger type header. The exit opening is then parallel to the ground. We used 308 SS sheet metal and tubing to form the transition, as the manifolds are stainless.

I'm thinking it's 24.5" wide between the front rails.
Having said that, if you wish, I can go out and measure in a few days. (stored in a remote location).
Manifolds were on an online auction, generally in the $150/pair range.
I did the fab work, is probably substantial to TIG weld. A friend did the TIG welding.

rough measurements:
from the bottom of the mounting flange to the collector - 7"
Then, using the mounting flange as a reference plane (i.e laying it flat on a table) distance from
plane to inside collector flange 1/2"
plane to outside collector flange 5 1/2"
He responded under a post I made regarding these manifolds.
