High-Performance JBA 1-7/8" Mustang Long Tube Headers

These JBA 1-7/8" Mustang Long Tube Headers feature mandrel-bent primaries and over-sized exhaust ports that not only create excellent airflow but also increases horsepower by more than 20-25 as JBA found during Dyno-Testing.

This header kit includes quality hardware, gaskets, and instructions for a straightforward installation.

Durable JBA Quality Constructed Mid-Pipe

JBA's Mid Pipe features mandrel-bent tubing that gives your exhaust a smoother outlet than the factory crimped mid-pipe. The mid Pipe features heavy-duty flanges and comes in a natural stainless steel finish that won't discolor over time. JBA experienced an average increase of 20-25 Horsepower during Dyno-Testing.

Off-Road X-Pipe System Features:

  • High-Performance Off-Road X-Pipe (Options Above)
  • Stainless Steel Tubing (Options for 3 inch or 2.75 inch above)
  • Factory Style Hangers

Not so sure
I bought them and had them installed. Didn't come with o2 extensions so I had to search for those, had them installed at a local performance shop and needed better clamps they say. To top that off there's a bit of an exhaust leak I can hear from the floorboard most likely from the gaskets... I'm thinking I should've paid the extra money for Kooks or ARH.
