Exhaust Header
LONG TUBE HEADER EXHAUST MANIFOLD FOR 11-16 FORD MUSTANG GT 5.0/302 V8 STAINLESS
A 4-1 long tube header exhaust manifold for the 2011-2016 Ford Mustang GT 5.0L V8 engine, built from stainless steel with a 1.75 inch inlet and 2.5 inch outlet. It replaces the factory exhaust manifold with a direct bolt-on design and ships complete with all necessary hardware, gaskets, and O2 sensor provisions. Fitment is specific to the 2011-2016 model years and does not cover the 2015 Mustang GT.

What You Get
Key Benefits
- 4-1 long tube design increases exhaust flow and reduces back pressure at high RPM
- 1.75 inch inlet and 2.5 inch outlet improve turbine spool and engine breathing
- TIG double side welding ensures strong, leak-free joints under heat and vibration
- CNC machined flange provides a flat sealing surface to prevent exhaust leaks
- O2 sensor insertions are pre-installed to maintain factory emissions monitoring
- Stainless steel construction resists rust and heat cycling better than cast iron
Why Buyers Switch
Problems It Solves
- Factory exhaust manifolds restrict flow and limit high-RPM power output
- Cast iron manifolds crack under heat cycling and fail after extended use
- Aftermarket headers without O2 sensor provisions require cutting and welding
- Generic headers need custom fabrication and increase shop labour time
- Missing gaskets or bolts delay installation and cause customer returns
Where It Is Used
Application Scenarios
- Performance shops upgrading 2011-2016 Mustang GTs for track or street use
- Distributors stocking vehicle-specific headers for the Ford Mustang GT 5.0L V8 market
- Online sellers needing a photographed, fitment-verified header with a clean product listing
- Tuning shops installing headers that match factory routing without custom fabrication
Buyers
Who It Is For
- Performance parts distributors buying Mustang GT exhaust hardware by the pallet

Final inspection of fit and finish before packaging
Checks
Quality Control
- Flange bolt pattern verified before welding
- Weld seams inspected for pinholes and gaps along the full joint
- Sealing face checked for flatness and surface defects

Comparison
Compared With The Alternatives
| Factory exhaust manifold | The stock manifold is designed for emissions compliance and lower noise, this header improves flow and power at the cost of higher exhaust note |
|---|---|
| Cast iron aftermarket header | Cast iron is cheaper but cracks under heat cycling; stainless steel holds up through repeated thermal stress |
| Universal header kit | Universal kits require cutting, welding, and custom fitting; this one bolts on directly with no modifications |
Installation
Use Guide
- Confirm the vehicle is a 2011-2016 Ford Mustang GT 5.0L V8 and not the 2015 model
- Disconnect the battery and let the engine cool before removing the factory manifold
- Replace the factory gasket and use the included metal gaskets for a leak-free seal
- Install bolts in a crisscross pattern to avoid warping the flange
- Torque all bolts to factory specifications after installation
