MBRP LB7 Duramax Turbo Down Pipe | 2001-2004 GM 6.6L LB7

The MBRP GMCA425 3″ Turbo Downpipe eliminates the restrictive factory downpipe in your 2001-2004 GM 6.6L Duramax LB7. Featuring a mandrel bent aluminized steel construction, the MBRP 3″ Turbo Downpipe provides a smoother flow from the turbo resulting in lower EGT’s and increased performance, throatier sound, and faster turbo spool-up. Each Downpipe is coated with a satin black high-heat coating and wrapped with a high-heat thermal wrap for added protection. A durable 1/2″ thick flange is used to eliminate warping and sealing issues. This Downpipe is a direct bolt-on replacement and is manufactured with precision bends for the perfect fit that you’ve come to expect from MBRP.
