The details
Streamline your exhaust upgrade and unlock hidden performance with the MBH Motorsports Stainless Steel Mid-Section with X-Pipe. While not strictly required to run our long tube headers, this mid-section is engineered to simplify installation by providing a direct, bolt-on connection between the back of your MBH headers and your factory resonator.
Upgrade your restrictive factory mid-section to premium, high-flowing 3-inch tubing designed to maximize exhaust velocity and deliver an aggressive track-ready sound.
Effortless Fitment: Designed specifically to mate with MBH Motorsports Long Tube Headers for a straightforward, bolt-on installation.
Superior Flow: Replaces the stock setup with upgraded 3-inch stainless steel tubing.
Secondary Cat Delete: Removes unmonitored secondary catalytic converters for reduced backpressure and enhanced exhaust scavenging.
Proven Gains: Deliver an estimated increase of 10–15 wheel horsepower (WHP).
