Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

The details
Specs & details
While not strictly required to run our long tube headers, the MBH Motorsports Stainless Steel Mid-Section with X-Pipe is the ultimate complementary upgrade for your exhaust system. Designed to seamlessly mate your MBH headers to the factory resonator, this mid-section makes installation incredibly simple while significantly improving overall exhaust flow and acoustic refinement.
By replacing the restrictive factory mid-section and deleting the unmonitored secondary catalytic converters, this system utilizes high-flowing 3-inch tubing to maximize exhaust scavenging. The integrated X-pipe design perfectly balances exhaust pulses from both cylinder banks, resulting in a smoother, more aggressive AMG exhaust note while unlocking an additional 10 to 15 wheel horsepower. Please note: Exact performance results may vary based on environmental factors, dyno type, fuel quality, and overall engine age.
Handcrafted USA Quality & Direct Fitment
Proudly handcrafted in the USA using premium 16-gauge 304 stainless steel, this mid-section is built to handle the intense heat and pressure of high-performance track driving. It is engineered for a direct, bolt-on fitment, bridging the gap from the back of your MBH Motorsports long tube headers straight to your factory resonator with zero custom fabrication required.
Key Features:
-
Performance Gains: Unlocks an estimated +10 to +15 wheel horsepower by maximizing exhaust velocity and efficiency.
-
Simplified Installation: Engineered as a direct bolt-on solution connecting MBH long tube headers directly to the factory resonator.
-
Integrated X-Pipe: Balances exhaust pulses to improve scavenging and deliver a refined, aggressive V8 exhaust tone.
-
High-Flow 3-Inch Tubing: Upgrades restrictive factory piping to smooth, 3-inch diameter tubing.
-
Secondary Cat Delete: Removes unmonitored factory secondary catalytic converters for maximum unrestricted exhaust flow on the track.
-
USA 16-Gauge 304 Stainless Steel: Proudly hand-fabricated in the USA for lifetime durability and extreme thermal resistance.
