04.5-2010 GM 6.6L Duramax MBRP 3 Inch 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.
