The MBRP GMCA424 3″ Turbo Downpipe eliminates the restrictive factory down pipe in your 2004.5-2010 GM 6.6L Duramax. Featuring a mandrel bent aluminized steel construction, the MBRP 3″ Turbo Downpipe provides a smoother flow from the turbo resulting in lower EGT’s, 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. Featuring CNC machined flanges, 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.
