LS Swap Exhaust Manifold Headers - 1982-1992 Camaro/Firebird (Third Gen)

LS Swap Headers for the Third Gen Camaro and Firebird

This is a set of exhaust manifold headers built specifically for LS-series engine swaps into a 1982-1992 Chevy Camaro or Firebird, the Third Gen F-Body platform. If you're dropping an LS1, LS2, LS3, or LS6 into one of these cars, factory manifolds and small-block headers aren't going to bolt up cleanly, and that's exactly the gap these headers are built to fill.

What's Included

Each header uses full 1 7/8 inch primary tubes feeding into a 3 inch collector, sized to move exhaust efficiently off an LS-series V8 without choking it down. That primary and collector sizing is a common sweet spot for street-driven LS swaps — big enough to flow well, not so oversized that you lose low-end torque.

LS Engines Only — Read This Before Ordering

These headers are built for LS1, LS2, LS3, and LS6 engines specifically, for LS-series swaps into the Third Gen F-Body. They will not work on a standard small-block Chevy (SBC) or big-block Chevy (BBC) — the mounting geometry and engine dimensions are different enough that a header built for an LS swap simply won't line up on a traditional small-block or big-block. If you're running an SBC or BBC in your Camaro or Firebird rather than doing an LS swap, this isn't the right header for your build.

A Clearance Note Worth Knowing Before You Install

If your swap uses a larger transmission — a 4L80E or an older Turbo 350 or Turbo 400 — the bellhousing ears may need to be trimmed for proper header clearance. This is a common enough step in LS swap builds that it shouldn't be a surprise, but it's worth planning for before you're halfway through installation rather than finding out mid-job. A die grinder and a bit of patience usually gets the clearance you need.

Why Headers Matter on an LS Swap

When you're already going through the work of swapping in an LS engine, running factory-style manifolds or a mismatched header defeats a lot of the purpose. A header built specifically for the swap gives you correct fitment against the LS block and heads, reasonable ground clearance for the F-Body's chassis, and enough flow to let the engine breathe the way it's meant to. Wikipedia's exhaust manifold article covers the general engineering tradeoffs between manifold and header-style exhaust routing if you want the deeper technical background on why tube length and primary sizing matter for flow.

Fitment

These headers are listed as fitting the 1982-1992 Third Gen Camaro, Firebird, and F-Body platform specifically, for LS1/LS2/LS3/LS6 swaps. If you're working on a Fourth Gen F-Body (1993-2002) or a different generation entirely, this isn't the correct header — Third Gen F-Body dimensions and mounting points are specific enough that fitment doesn't carry over between generations.

Installation Notes

Beyond the bellhousing clearance note above, expect a header install on an LS swap to require careful attention to ground clearance, steering shaft clearance, and starter motor fit, all of which vary depending on the rest of your swap components. If this is your first LS swap, it's worth researching build threads for the Third Gen F-Body specifically before you start, since a lot of the fitment quirks are well documented by people who've done this exact swap before.
