MBRP GM8424 3 Inch Down Pipe for 2004.5-2010 Duramax 6.6L Diesel

The MBRP GM8424 is a high-performance 3-inch down pipe designed specifically for mid to late 2004 through 2010 Chevrolet Silverado and GMC Sierra trucks equipped with the 6.6L Duramax diesel engine. This upgraded down pipe is engineered to enhance exhaust flow and reduce backpressure, allowing your turbocharged diesel engine to breathe more efficiently and produce more power.

Constructed from heavy-gauge aluminized steel with a durable black powder coating, this down pipe combines performance with longevity. The mandrel-bent tubing ensures smooth, unrestricted exhaust flow with no rippling or crimping in the bends, maximizing your engine's ability to expel spent gases and draw in fresh air for improved combustion.

Key Features:

• 3-inch mandrel-bent aluminized steel construction for maximum flow
• Black powder-coated finish for corrosion resistance and aggressive appearance
• Direct bolt-on installation for 2004.5-2010 Duramax 6.6L engines
• Enhances turbo spool and improves throttle response
• Deeper, more aggressive exhaust tone
• Reduces exhaust gas temperatures (EGTs) under load

This down pipe is backed by MBRP's 1-year warranty on the black powder coating and a 3-year warranty on structural components. The increased diameter over the factory down pipe allows for significant improvements in exhaust flow, which translates to better fuel economy, increased horsepower and torque, and improved engine longevity.

Note: Not legal for sale or use in California. Fits mid to late 2004 models only.
