  • Overview
  • Features

Remove the restrictive OEM downpipe and replace it with MBRP's GM8425 3" Downpipe. This will help your LB7 breath by increasing the exhaust flow of your turbocharger. Featuring full 16 gauge mandrel bent tubing to maximize flow, as well as an extremely durable high-temperature ceramic coating, these pipes will deepen the sound of your Duramax while lowering EGT's and provide a quicker throttle response. The install process is as simple as it gets from the precision bending that you'd expect from an MBRP kit.

  • Mandrel Bent To Maximize Flow
  • Ceramic Coated
  • Improved Heat Retention & Dissipation
  • 20% Greater Flow Over Stock
  • Increased Performance
  • Throatier Sound
  • Faster Spool-Up
