      Description

      Greater Turbo Response and Horsepower. The Boosted Performance 3-Inch Downpipe is engineered to dramatically enhance the efficiency of your Duramax LML's turbocharger. By replacing the restrictive factory downpipe with a wider 3-inch diameter, this upgrade improves exhaust flow, allowing the turbo to spool faster and more freely. The result is a noticeable increase in horsepower and torque—typically 10–20 horsepower and 20–30 lb-ft of torque—along with reduced turbo lag and cooler exhaust gas temperatures.

      Built to Last. Constructed from premium stainless steel, the Boosted Performance 3-Inch Downpipe delivers strength and long-term corrosion resistance under extreme heat and weather conditions. Its robust build ensures that it performs reliably over time, even in high-stress driving environments, making it a lasting investment in both performance and durability.

      Better Thermal Efficiency. The Boosted Performance 3-Inch Downpipe includes a high-performance heat wrap to help manage under-hood temperatures. This thermal barrier not only protects nearby components from heat exposure but also promotes better exhaust velocity by keeping gases hotter within the pipe. It’s a smart enhancement that supports cooler engine bay conditions and optimal thermal dynamics.

      Installation. Putting this Boosted Performance 3-Inch Downpipe on your 6.6L Duramax Silverado 2500 HD takes 3 hours to install.

      Warranty. There is a limited warranty on this product.

      Application. The Boosted Performance 3-Inch Downpipe fits 2011-2016 6.6L Duramax Silverado 2500 HD models.
