Improves Horsepower. With the MAC 15/8 inch 351W/5.8L Swap Chrome Long Tube Headers installed on your Ford Mustang, you’ll benefit from improved horsepower, torque, and exhaust flow. The design enables 351W engine swap and 190 LPH pump modifications in your Mustang.

Heavy-Duty Construction. The headers are made to last for the long haul with durable 16 gauge steel. Solid flange headers tend to loosen. This is not a problem with the innovative single port flanges in these headers. Gaskets are susceptible to blow outs and leaks. With the MAC true fit design of these headers, the need for gaskets are eliminated. The MAC 351W swap header includes threaded flanges so that they can be attached without the need to weld them.

Straight Forward Installation. You can complete this straight forward installation with basic hand tools and general mechanical knowledge. All the required components and mounting hardware are included to facilitate the installation.

1 Year Limited Warranty. The manufacturer provides customers with a limited one year warranty which provides coverage for any craftsmanship defects. Check through the warranty information to ascertain what types of limitations apply.

Application. The MAC 1-5/8 inch 351W/5.8L Swap Chrome Long Tube Headers are designed to fit all 1979-1993 Ford Mustang models with manual transmissions only. They are designed for off-road use only.
