Diamond Eye Turbo-Direct 3" Aluminized Downpipe for 2004-2010 Chevrolet/GMC (6.6L Duramax LLY/LBZ/LLM)
$480.48
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2004-2010 Chevrolet Silverado and GMC Sierra 2500 HD, 3500, and 3500 HD (6.6L Duramax LLY / LBZ / LLM).
The Diamond Eye Turbo-Direct downpipe is engineered to replace the restrictive factory pipe, significantly improving exhaust flow and reducing backpressure directly from the turbocharger. Constructed from 3-inch aluminized steel, this component is fabricated using precision CNC mandrel bending to ensure smooth transitions and consistent tubing diameters. This design helps lower exhaust gas temperatures (EGTs) and improve turbo spool-up response, providing a more efficient path for spent gases to exit the engine.
