What You Get
Key Benefits
- 2.25 inch bore maintains high exhaust flow without restricting engine output on the 4.6L GT

- V-band inlet flange allows quick disassembly for maintenance or tuning
- Socket outlet flange with included gaskets and hardware enables a secure bolt-on fit
- Dual pipe design improves scavenging and reduces back pressure during high RPM operation
Why Buyers Switch
Problems It Solves
- Factory exhaust manifolds and pipes restrict flow and reduce engine efficiency at high RPM
- Mild steel x-pipes rust at the flange and fail within a few seasons in humid or salty climates
- Universal x-pipes require cutting, welding, and custom fitting, which increases labor cost
- Lack of included gaskets and hardware leads to incomplete installations and leaks

Comparison
Compared With The Alternatives
| Factory exhaust system | The stock system is emissions compliant but restricts flow; this x-pipe improves exhaust velocity and engine breathing for performance |
|---|---|
| Mild steel aftermarket x-pipe | Mild steel is cheaper but corrodes at the flange; stainless steel holds up under heat and moisture exposure |
| Universal cut-to-fit x-pipe | Universal pipes require welding and fitting; this one bolts on without modification |
Installation
Use Guide
- Confirm the vehicle is a 1996-2004 Mustang GT or Cobra with the 4.6L V8 engine
- Do not install if the vehicle is registered in California or New York
- Remove the factory exhaust system before installing the new x-pipe
- Install new gaskets and torque hardware evenly to prevent leaks
- Check for exhaust leaks after the first heat cycle and re-torque if needed
