2015-2026 Ford Mustang Stainless Works GT Headers 1-7/8in Primaries 3in Catted Factory Connection

This listing covers the exact Stainless Works headers & manifolds configuration identified as Ford Mustang Stainless Works GT Headers 1-7/8in Primaries 3in Catted Factory Connection.

Catalog fitment covers the listed 2015-2026 Ford Mustang applications. Exact year and submodel combinations appear in the fitment table below; compatibility must not be inferred for every trim across the full range.

Manufacturer-supplied details include 1-7/8in primary tubes carry each cylinder's exhaust into the collector, sized for the Mustang GT's 5-liter engine; 3in catted piping keeps the catalytic converters in the system instead of deleting them; The factory connection point ties into the rest of your stock exhaust setup past the headers.

This header system steps up to 1-7/8in primary tubes and 3in catted pipes that meet your exhaust at the factory connection point downstream. Because it reconnects there, fit depends on that part of your exhaust still being in factory form: if you have already swapped in an aftermarket mid-pipe or cat-back, check that the connection still lines up before you order. This product is emissions-sensitive. Check your local emissions laws before you buy. Swapping the factory manifolds for a header system also changes how the car sounds, and that change carries into the cabin on the highway, not just outside it.

Listed specifications include Part type: Headers & Manifolds; Primary tube diameter: 1-7/8in; Catted pipe diameter: 3in; Downstream connection: Factory connection; Emissions status: No CARB EO number on file. Check your local emissions laws before you buy.

Use manufacturer part number M24HCAT to identify this exact Stainless Works configuration. Match the full part number, vehicle application, position, dimensions, material, finish, and included components before ordering.
