Old vs. new A-pipes. The hole right before the flex-pipe is where the oxygen sensor goes.

The old manifolds are unequal-length and the primaries are maybe as long as an inch. Not tuned at all! The new manifolds are probably about six inches long, and are equal-length.

All done! No heat shield. The precious CARB E/O # is stamped below the Comptech USA logo on the middle pipe. The headers fatten up the midrange and let the engine breathe a lot better at high revs (especailly since I have CL-S cams too), and part-throttle response is improved.
