Product Specifications

3-Inch Duramax Downpipe for Silverado and Sierra 2500 HD / 3500 HD

This silver, single-pipe downpipe replaces the turbo outlet exhaust section on the listed Chevrolet Silverado and GMC Sierra 6.6L turbo diesel trucks, including configurations sold as LLY, LBZ and LMM. Its mandrel-bent stainless steel tube provides a defined replacement path from the turbo connection toward the intermediate exhaust pipe. Confirm the vehicle configuration and both exhaust connections before ordering.

Key Features

  • Turbo outlet replacement section: identifies the exhaust section to compare with the pipe currently fitted to the truck.
  • Mandrel-bent stainless steel tube: provides a consistent formed route through the downpipe bends.
  • Single-pipe configuration: lets you select the downpipe without an up-pipe or intercooler bundle.
  • Silver finish: distinguishes this option from the separately listed black pipe.

What Is Included

  • One silver downpipe for the selected single-pipe option.
  • Clamps, gaskets and mounting hardware as described in the current product listing.

Check Before Ordering

  • Match the truck to a listed Fitment row and verify the 6.6L engine code, especially at model-year changeovers.
  • Confirm the turbo outlet and downstream exhaust connection against your truck.
  • For a 2004.5 truck, check the build date and engine code. The original FAQ excludes Cab & Chassis trucks; ask Flashark to resolve that restriction for your VIN before ordering.
  • Check the selected Style and every included component separately. Bundle options add parts beyond the single downpipe.
  • Confirm the exact hardware quantities and fit with the existing exhaust system before ordering.
  • This product is presented for off-road use only. Confirm the rules applicable to your vehicle and location with Flashark; the listing does not provide a vehicle-specific road-use approval.
