XDR Replacement Up Pipes | 2001-2004 Chevy/GMC Duramax LB7

The XDR Replacement Up-Pipes increase both the flow and reliability of your 2001-2004 6.6L GM LB7 Duramax. Even a stock Duramax can produce high temperatures and pressures that cause OEM up pipes to eventually fail from constant temperature and pressure fluctuation.

Features

• Bolt-On Replacement (Non-EGR)
• Faster Spool-Up & Increased Performance
• Significant Reduction In Exhaust Back Pressure
• Free-Flowing Stainless Steel Inner Liner Bellows

Note: These race up-pipes do not retain the use of the EGR. They are for off-road use only and will only work on non-EGR applications.
