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.
- 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
15 vs 15.5 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.
