This pipe runs from the left exhaust port down to the muffler, carrying spent gases away from that cylinder. It's a left-side-specific part, so don't try to swap it with its right-hand counterpart — the two are not the same piece even though they look similar at a glance.
If your parts book lists this one under the older 71-3755/8 number, that's the same physical pipe under its earlier factory designation. Check your muffler and crossover tube setup before ordering, since exhaust systems changed across these model years and you want the header that matches the rest of your system.
