MBRP 3" Turbo Down Pipe - 50 State Legal - 11-15 GM Duramax 6.6L LML - GMCA427

MBRP 3" Turbo Down Pipe
50 State Legal
2011-2015 GM Duramax 6.6L LML

NOTE: The GMCA427 downpipe is only for the 2011-2015 models with the standard v-band connection. It will not work on late model 2015.5 trucks with the 3-bolt flange.

The MBRP GMCA427 3" Turbo Downpipe eliminates the restrictive factory downpipe in your 2011-2015 GM 6.6L Duramax LML. 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.
