3" MBRP Duramax Downpipe

Remove your restrictive factory downpipe and let your Duramax breath with the true 3" MBRP downpipe. Your downpipe will come with a satin black ceramic coating and then wrapped in high-heat thermal wrap to keep the heat in.

Benefits include:

• Deeper Throatier Sound (Who doesn't love that alone?)
• Lower EGTs
• HP and Torque Gains
• Faster Turbo Spool up
• Smoother exhaust flow from the turbo

2015 vs 2015.5 trucks: 2015 trucks will have a V band style clamp connecting the bottom of the downpipe to the exhaust system.  2015.5 trucks will have a 3 bolt flange in place of this.
