04.5-2010 GM 6.6L Duramax MBRP 3" Turbo Downpipe (50 State Legal)

This MBRP downpipe eliminates restriction compared to the factory downpipe. This downpipe is made of mandrel bent aluminized steel construction which provides a smoother flow from the turbo which results in lower EGT's, increased performance, throatier sound and faster turbo spool-up. 


Downpipe is coated with satin black high-heat coating and is also wrapped with high-heat thermal wrap. Durable 1/2" thick flange is used to eliminate warping and sealing problems. This downpipe is a direct bolt-on replacement.
