Construction & Design

The JBA Mid-Pipe is expertly crafted from 409 series stainless steel, a material known for its excellent resistance to rust and heat, making it well-suited for the demanding conditions of off-road and street driving. The mandrel bending process preserves the internal diameter of the tubing throughout bends, reducing turbulence and backpressure to maximize exhaust flow efficiency.

Each mid-pipe features heavy-duty flanges that provide a secure seal and long-lasting durability. Factory-style hangers are integrated to maintain proper alignment and reduce vibration, ensuring a professional fitment that matches the original equipment. The hand-polished mirror finish not only enhances corrosion resistance but also adds a sleek, custom look under the vehicle.

Performance & Sound

By opening up the exhaust flow, the JBA Mid-Pipe improves engine breathing, which can lead to enhanced throttle response and a more robust exhaust tone. When paired with aftermarket headers, this mid-pipe helps unlock additional performance potential from the 4.0L engine. The result is a deeper, more aggressive exhaust sound that enhances the driving experience without excessive drone.
