    Description

    More Power and Sound. This 3-Inch Turbo Downpipe; V-Band Flange Connection is what you seek if you're looking for some more power and sound out of your Sierra. You will see dyno-proven instant increases of 20-25 horsepower/low end torque, which improves performance and gives you a new deep sound.

    Construction. This Downpipe is built from 3-inch stainless steel with computerized mandrel bends. This means strength, while the downpipe removes restrictions and reduces exhaust gas temperatures. There is a high-performance racing spec design and a TIG-welded, CNC-machined flange to combat pressure and corrosion.

    Installation. This can be quite a tricky installation, so professional help is recommended.

    Application. This 3-Inch Turbo Downpipe; V-Band Flange Connection fits 2011-2015 6.6L Sierra 3500 HD models.
