MBRP 3 Inch Turbo Down Pipe for Duramax

The MBRP 3 Inch Turbo Down Pipe for Duramax is a direct bolt-on replacement for the restrictive factory turbocharger down pipe (turbo downpipe, turbo direct pipe). It is designed to improve exhaust flow from the turbo on 6.6L Duramax diesel engines. It is also CARB compliant.

Key Features:

• 3 inch mandrel-bent tubing keeps the bends smooth and the flow free from the turbo.
• Aluminized steel construction resists corrosion and heat.
• High-heat coating protects the finish.
• Direct bolt-on design replaces the factory piece without cutting or welding.
• CARB compliant and backed by a CARB Executive Order, so it is intended for emissions-legal use, including in California.
• MBRP warranty coverage on the product.

A less restrictive down pipe can lower exhaust gas temperatures (EGTs) and help the turbo spool up faster. It can also improve throttle response and give your diesel a deeper tone. MBRP designs and builds performance exhaust parts for diesel trucks, and this down pipe is a straightforward upgrade over the stock unit.
