MBRP GMCA424 3 Inch CA Down Pipe

The MBRP GMCA424 3" Turbo Downpipe eliminates the restrictive factory downpipe 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.
