Wehrli 3-Inch V-Band Down Pipe — 2011-2015 Chevrolet 6.6L LML Duramax

Improve exhaust efficiency and turbo performance on your 2011-2015 Chevrolet 6.6L LML Duramax with the Wehrli Custom Fabrication 3-Inch V-Band Down Pipe. Featuring a convenient V-band connection at the turbocharger outlet, this down pipe offers superior sealing and easy installation/removal compared to traditional flange designs — a huge advantage during turbo swaps or maintenance. The 3-inch diameter dramatically reduces exhaust restriction compared to the factory unit, resulting in improved spool, power, and lower EGTs.

Key Features

  • 3-inch V-band style connection at the turbocharger outlet for easy install/removal
  • Designed specifically for the 2011-2015 Chevrolet 6.6L LML Duramax
  • V-band connection provides leak-free sealing superior to OEM flanges
  • Reduces exhaust back pressure for improved turbo spool and horsepower
  • Lowers exhaust gas temperatures under towing and performance conditions
  • Mandrel-bent construction for smooth, unrestricted exhaust flow
  • Ideal for turbo upgrades and performance builds

V-Band: The Smarter Connection

The V-band design is favored by diesel performance builders for good reason — it creates a stronger, more reliable seal than traditional flange connections and makes turbo removal and reinstallation significantly faster. For anyone planning turbo upgrades or frequent maintenance on their LML, this is the preferred down pipe design.

Fitment: 2011-2015 Chevrolet 6.6L LML Duramax
