MBRP GMCA427 3" Turbo Downpipe

For 2011, 2012, 2013, 2014, 2015 GM 6.6L Duramax LML (50 STATE LEGAL)

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.
